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!
