This is a page of the morse keys I currently own.

Walters Electrical Key (rond 1900) (post office key):

Junker Key :

the well known military junker key

Japanese Key :

believe it or not is is stamped made in Japan (a 5$ key)

Unknown Key :

This key was given to me by a friend, it was nickel plated and in very bad shape so I decided to take off all the nickel plating and this is the result after 6 hours of sanding, the knob is made by me too.

It is unclear if this was a homemade key or maybe a school project but it was nicely done, if someone has more info pse e-mail me.

East German K64 Key :

Made in the DDR
