1918 1920 double stamp internal frame numbers
 

today i decided to fully field strip and clean and inspect my 1918 1920 double stamp and to be sure all the numbers are matching and take some better pictures, since i am starting to get a grip on the macro. All my nubers are matching , except the grips , every thing looks to be in great shape and good working order, I noticed some stamps in the lower part of the frame and bottom of the reciever and i was wondering about them, again thanks for your help , Regards Padre

These are assembly marks, present on all Lugers.

To date, there are no references that give any specific meaning to most of these.

Thanks, i allso disassembled my 1929 dwm police, it had very few if any of the stamps. Is it perhaps because it is a commercial? Very few of the parts on it are numberd , but the ones that are all match.
