Does any one know the correct serial range
 

for the 1920 carbine. Theres allot written about it earlier cousin. I can't even get a handle on how many were even made as compared to the 1902. Did they all have grip safetys? I read that some we made in both the 9mm like mine and the 7.5mm. Besides calibre where there any other differences beteen the 2 models. Are there records how many were produced or sold? How were they sold? Was there an American distributor? Were most made for export? How come so little is written! I can't even find one to compare. I'm aware there a some who argue that this model doesnt exist!! Well I know of one! TKS Eric,
