Welcome to my online crypto museum! Here you will find some information about a number of old encryption items, including manuals, posters, and machines. I hope you enjoy your visit!
I try to put as many original source materials online as I can. I have posted some manuals here, some of my favorite propaganda, magazine articles, and even a training video for the M-209 encryption machine.
As I tried to learn more about these crypto machines on the web, I found that there were very few hi-resolution images for me to study. Part of my goal for this site is to provide such images.
If you have ideas for the site, or if you'd like me to post photographs of a specific item, please feel free to contact me by filling out the form below. I would enjoy hearing from you!
