Here is a group shot of 3 CD 438s from Finland. Sources have told me that they may have been made in Russia, and were used by the Finnish Army. One of my three, has an embossing of 5 small vertical bars on it.

I'd like to do a survey to find out how many of these are out there in collections and what people think they might be worth. E-mail me if you have one of these, and especially if you have any more info on their origins and use.
