Fialka Cover, Accessories, and Multi-Adjustable Modular Wiring Matrix
Descriptions, and Photographs:
The following section describes and displays the metal cover for the Fialka
and a set of accessories that may accompany the machine. Other sections listed
in the FIALKA MENU above show descriptions and photographs of the the Model M-
125-MN and Model M-125-3MN/-3MP3 Fialkas, the Rotors, and the 24 Volt Power
This sheet shows a list of the items that are included with
a model M-125-3MP3 fialka.
This is the tool kit used for maintenance and adjustment of the Fialka.
A metal cover protects the Fialka from damage in transit and contains a
variable number of accessories.
The back of the cover has two metal skids that hold it up.
The inside of the cover may contain accessories as shown. These
accessories may include a hand crank, a special test reflector, additional
print wheels, and a different set of rotors.
This is the hand crank that may be found inside the cover.
The additional print wheels, if included, are stored inside protective
white plastic covers and stacked on a shaft.
A special black or brown colored TEST REFLECTOR may also be stacked on the
same shaft as shown. To use this test reflector, all rotors are removed from
the rotor shaft, the 'E' clips are installed to hold the test reflector at the
far right end of the shaft, and the shaft is placed in the Fialka. The test
reflector has every pair of adjacent contacts connected together. The
voltages from the Input Wheel are therefore 'reflected' directly back to the

This is a closer view of the additional print wheels.
This is a closer view of the input or right side of the special test reflector. These contacts receive voltages from the Input Wheel and reflect them right back to adjacent contacts on the input wheel.
To use this test reflector, all rotors are removed from the rotor shaft, the
'E' clips are installed to hold the test reflector at the far right end of the
shaft, and the shaft is placed in the Fialka. The test reflector has every
pair of adjacent contacts connected together. The voltages from the Input
Wheel are therefore 'reflected' directly back to the input wheel.
This is a closer view of the left side of the special test reflector.
Notice that adjacent pairs of pins are connected together so that a voltage
coming in on one pin is reflected back out on the adjacent pin.
This is the box that catches the paper tape chad (Punched-out pieces of
paper) for the M-125-xxx Fialka.

The special Rotor Page describes all sets of rotors in
detail and shows their wiring and stepping data.
The additional set of rotors, if present, is stored in a protective metal
This is a brief description of the special set of Multi-Adjustable Modular
Wiring Maze rotors. The retaining clip that holds the rotors on the shaft is
shown on the right side of this picture.
(Information on the Non-Adjustable rotor set and wiring and rotation data
for all sets is shown and described in the special detailed
page explaining the rotors:)
This is a "3K" series rotor as indicated by the "3K" inscribed on its input side. These "3K" series rotors are known to have come from Poland.
Another series that has a "6K" inscribed on its input side is known to have come from the former Czechoslovakia. This suggests the possibility that these two rotor series were used in different countries or by different military organizations.

rotors after they have been removed from the shaft.
This photograph shows the special retaining clip location that allows 8 of
the rotors to be mounted on the shaft instead of 10. An accessory spacer
fills in the rest of the rotor stack width.

Maze rotors after they have been removed from the shaft.

The adjustable outer ring setting on one of the 10 Multi-Adjustable
Modular Wiring Maze rotors. Pushing the pin inwards allows the outer ring to
be rotated to any of the 30 positions.
(The pin can only be pushed inwards AFTER the removable reversible wiring maze module has been removed.)
The removable reversible wiring maze module is shown being removed from one
of the 10 Multi-Adjustable Modular Wiring Maze rotors. It is removed by
releasing the metal retaining disk. This disk is released by rotating it to
the right or left.
Much more information on rotors, rotor
movement, and the exact internal wiring data is given in: this special rotor description and data page:
