The Fourth Annual
Crypto-Conference, Sale and Forum.

The 2016 "HamRadio-2016" meet at Friedrichshafen Germany was the site of the fourth annual Crypto-Conference, Sale and Forum.

Report on the First Annual (2013) Friedrichshafen Conference, Sale and Enigma Forum
Report on the 2011 Friedrichshafen Conference and Sale

The meet was held from June 23-26, 2016 in the huge "Messe" (Convention Center) adjacent to the airport in Friedrichshafen which is on the bank of the lovely Bodensee (Lake Constance).

This year we reserved 8 tables in the flea market for the display and sale of crypto-related apparatus, spy radios and other items. A huge "ENIGMA" banner flew over the tables so you could see them from across the large hall. There were two huge halls with about 1000 tables displaying equipment for sale so the big "ENIGMA" sign helped people locate our tables. A wide variety of exotic crypto gear, spy radios and other interesting items were on display and on offer. During the four days of the conference a great deal of Crypto gear and many spy radios and other items changed hands and both sellers and buyers came away very happy.

The buyers were almost all members of the Cryptocollectors Email reflector on Yahoo-Groups so they all knew exactly what they were buying and the appropriate values. Many of the sellers were also on the reflector but some spectacular items were also brought to the show by other sellers such as crypto-expert Professor Dr. Franz Pichler of the University of Linz, Austria who brought some very fine relatively modern crypto-gear.

In addition to the buying, selling and networking in the flea market, the Fourth Annual Enigma Forum was held on Friday afternoon at 1600. It was very well attended with a crowd of over 200 people who watched the lectures and the demonstrations.

I hope that this report will encourage you to consider attending next year. I do not believe that there has ever been such a broad selection of fine and unusual crypto- gear for sale in one place along with such a gathering of crypto- experts and historians. In my opinion, this conference is a lot more fun than Ebay, the food is better, and you can bargain face-to-face with the sellers. Don't even think of coming without a shopping bag full of Euros or you will be kicking yourself about the things you wanted but could not buy because the sellers only accept Euros.

Below you will find some photographs of the items that were offered for sale as well as pictures of the sellers and buyers and the Forum.

This is one of our rows of 4 tables of crypto-related goodies.

This is our other row of 4 tables of crypto-related goodies.

This a photo of one of the two halls enclosing the flea market. There were approximately 500 3-meter-long tables in each hall.

There was always a crowd in front of our tables.

Klaus Kopacz was kept busy explaining and demonstrating all of the features of his exact Enigma Replica.
To the left of his replica you can see his NEMA.
To the right of his replica you can see his exact replica Enigma battery, his hand-held cipher machines and a number of battlefield-dug Enigma rotors and parts.

Marc Simons (right) and Paul Reuvers (at far end of table) showed and demonstrated their popular Enigma-E kits, their FIALKA book and some fine spy radios.

In the foreground is their amazing and deceptively childish-looking E-118 Cryptographic Barbie Electronic Typewriter.

Although it appears to be just a children's toy, it contains a number of sophistocated enciphering and deciphering abilities. You may read about it on Paul and Marc's webpage:

The techniques for activating the encoding and decoding abilites, the Mono Alphabetic Substitution Cipher (MASC) technology and the Substitution Tables are explained in:

At the end of Paul and Marc's tables, three vintage teletype machines ran continuously. They were very popular with the crowds.

Here is another view of two of the teletype machines in action.

John Alexander displayed an absolutely mint in-the-original-box M-209. We all watched as he broke the seals and opened the box for the first time.
He also displayed a red telephone and a set of exceptionally rare rotors for the Abwehr Enigma "G".

Klaus Kopacz (right) shows off his immaculate cipher machine to John Alexander. The machine is mounted in a lockable metal case that is clearly marked for the German Embassy in Moscow. Dug up relic Enigma parts are on the left and his NEMA is on the right.

Tom Perera (left) and Dan Perera (right) in front of their display. From left-to-right, an R-014 Russian Burst Encoder, a working 3-rotor Enigma, a FIALKA and two FIALKA power supplies.

Ray Robinson, a Cryptocollector from Australia shows off one of his finds.

David Cripps, another Cryptocollector, finally made it to Friedrichshafen this year. Here he shows off a FIALKA rotor with 60 possible wiring configurations that he bought at the show.

Mark Simons (left) and Paul Reuvers show off (most of) a very rare and unusual spy radio that they found on a table at the meet. This set is so rare that it was an exciting find even though it was not in good condition.

This man came over to our tables with a big smile and an Enigma for sale.

As you can see, it was in very poor condition and he wanted a very high price for it so he ended up taking it back home with him.

Here is a view of the inside of the Enigma. All parts were so heavily corroded so that nothing would move.

Another man stopped by our tables to offer us a very rare Enigma UHR box. The UHR box is a switch that replaces all of the steckers in an Enigma and allows the operator to set certain stecker plug settings by turning a switch knob rather than inserting stecker plugs into the steckerboard.

We looked at it very carefully and saw that top of the case was in very poor condition.

Then someone noticed that the stecker plugs were longer than the ones used in 3-rotor Enigmas. The stecker plug on the left is one of the steckers that are attached to the UHR box and the stecker on the right is a typical 3-rotor Enigma stecker.
The long steckers were only used with German Marine Enigmas so this UHR box was apparently made to work with German Navy Enigmas. However, UHR boxes were only known to have been used with the three-rotor Enigmas used by the German Air Force and there is absolutely no previous evidence that UHR boxes were ever used by the German Navy.
Since this UHR box came from Norway it might have been used with the 4-rotor M4 Enigmas that were in service with the German Navy in Norway.
The discovery of this unique UHR box leaves us with another puzzle that will need to be researched further in the future.

One of the most surprising discoveries was a box of the special oil cans used in maintaining FIALKA cipher machines. Previously, the only known example of this very rare FIALKA accessory was the oil can shown on Paul Reuvers' and Marc Simons' website;
I bought every one of them and the owner promised to bring more to Friedrichshafen next year. I intend to offer them to FIALKA owners next year when I am able to buy more of them.

These oil cans came from a FIALKA depot and the owner bought them in a large batch. He then pasted his own label on them and gave them to customers to advertise his automobile repair service. Since he is no longer in that business, he agreed to sell the remaining cans to me. His labels can easily be peeled off.
This is another example of the very unusual and unpredictable items that show up at this meet.

Here is a former Enigma operator who saw our sign which asks anyone who worked with Enigmas to tell us their story.
Klaus Schmeh interviewed him and will write up his story.
Over the years we have been able to find and interview quite a number of former Enigma operators and repairmen.


Here are two suitcase-mounted clandestine radio sets.
The one on the left is a rare pre-WW-2 clandestine transceiver with an asking price of 2,500 EU. This translated into about 2,800 US Dollars.
The one on the right is a body-worn cold-war era clandestine Russian direction finding receiver complete with all accessories including the safty-pin mounted antenna which was designed to be pinned inside the arms of an overcoat. The asking price was 1,500 EU or about 1,700 US Dollars.

Here are several clandestine receivers for sale.

Here is a box of Cold-War era FIALKA Era telegraph keys on offer for 10EU each.

Here is a nice little MITE portable teletype set for sale.

Many tables like this one were stacked high with original German WW-II radio equipment. Most of the prices were quite reasonable.

Most of the versions of the Volksemphanger propaganda radios were on sale as well as several R-2 propaganda sets as used in U-Boats like the one on the far left of this picture. Again, most of the prices were quite reasonable.

Many old and interesting telegraph keys were for sale on various tables at very reasonable prices.

This rare old military portable telegraph set was for sale for 800 Euros.

Many very early radios were being sold on various tables.

Early scientific instruments were tucked in among the radio sets.

On a somewhat different note, here is a complete violin-making kit for sale. You never know what may turn up at this meet.


Here are the presentations made at the Fourth Annual Enigma Forum.

Tom Perera started the forum by presenting a close look at the electrical circuits and wiring of an Enigma followed by some very recent findings in Enigma history.

Mark Simons (right) and Paul Reuvers gave an exceptional in-depth analysis of the history and technology of the British Typex machine and, for the first time, revealed the direct interoperability of the British Typex, the German Enigma, and the American Sigaba.

Klaus Schmeh presented in graphic detail the story of 7 crimes that involved enciphered messages.

The forum ended with Klaus Kopacz (in the yellow shirt) demonstrating his exact Enigma replica and his replica Enigma battery to a very large, appreciative and enthusiastic audience.
