I recently purchased this NOS (new old stock) RM-31 Czech Military Key from Mike, G0CVZ.

These keys were made in the late 1950’s and are still in the factory wrapping. The price was a very reasonable $US45 including shipping to Canada.

So far I am extremely impressed with the key. I would compare the feel to German Keys such as the Junker and the Baumuster T1. Construction is excellent and the key is very stable on the supplied painted steel base so there is no need mount it on a wooden base. The key comes with a cord and plug attached. The plug is a dual prong, with the diameter of the prongs being roughly the same size as a banana plug so if you wish to keep the key “original” then you would need to build some sort of adaptor box consisting of a couple of banana jacks and short cord with an appropriate plug for the key jack on your rig.

This is a very impressive key at an incredible price.
