You definitely got that right ! Historic value is massive. This gun belonged to my wife´s grandfather. There is no documentation between the period 1916-1940, but on 4th july 1940 grandfather bought (there is a receipt, sale price was 100mk = 20$) this gun from the FinnishWhite Guards. 1945, after Finland lost war against Russia
, it was hidden under the floor boards and remained there for 7 decades.
Since the gun has verified history all the way to 1940 (and also the period 1916-1940 is quite easily figured out) it was not too bad to get legal permit to hold on to it. Firing is prohibited though...
