A collector who just bought a Fialka cipher machine asked me how to load the paper tape, which is tricky until you’ve done it a few times. Here’s how I load the wide paper tape (for printing and/or punching) into my Czechoslovakian M-125-3 machine. His machine is a Polish M-125, but hopefully the paper path is about the same (I’ve never handled the earlier model of Fialka, so I’m not sure about that). The paper tape path is a bit different when using the narrower print-only paper tape, but I don’t have any to demonstrate with.
The USSR M-125 series “Fialka” cipher machines.
The “Fialka” is a cipher machine which was made and used by the USSR during the Cold War. I found this one on eBay, and it only required minor repairs to become fully operational. I’ll write more detailed information about it later; in the mean time, here are some pictures of my Fialka. You can also find more details about this kind of machine on Wikipedia.
