Your issue is that you more than likely purchased a cartridge with a 0.366" diameter while your example required a 0.358" diameter. There's a excellent series of articles by Mike Ford in the a current GGCA(
http://www.germanguns.com ) publication on the varieties and design of post standardization loadings, which were an attempt to span the diameter spectrum. There was such a variation of bullet diameters until the cartridge was standardized. There should also be a "72" stamp on there somewhere. Hammers really aren't an indication of age as if I recall correctly, ALFA, Bornmuller, etc., retailed an offering in the 1920s. Can you email or post pics?
It sounds like a Sauer Model 19 if it has a dolls-head extension.
