This is a M1914? but how can I find out it's origin? I have seen many photos of others but this one is slightly different and with belt holster. The difference with this is that it is stamped D.R.P.u.A.P after the Cal 7,65, also has 324 stamped twice and the holster has an unusual long tassel. I know it is European and most likely German (guessing). Can anyone tell me is this WWI? or pre WWII? Anything special about this I am missing?
