It could very well be French- the Velo Dog cartridge, and the first of the revolvers WERE French, made by Galand. The Belgians were soon making inexpensive copies (at that time, everyone in Belgium over the age of 5 seemed to be in the gun business)
I have had a couple of SIMILAR guns (ejector mechanism is somewhat distinctive) that did have Belgian proofs- two velo dogs and 2 in .320 European Revolver caliber. A lot of the Belgian guns used a fluting that was closed at both ends- most is open at the front end.
Not a guarantee, just an indicator.
And BETTER PICTURES would help (HINT!)
Alright, thank you, now i need to do even more research on this little thing.
Wow! Thanks a lot to everyone! All I knew about it before now was that my grandfather "removed" it from a German boy that tried to use it on him. I assumed it was a military issue boot gun for the Germans. Now, i guess the assumption should be that this was the kids personal gun that he brought to the field.
