Double Date Question

[ithacaartist]

OK, that clears that up for me. Without pics, did not realize the "1917/20" was a literal transcription of the stamping, complete with slash, but understood it as the much more commonly rendered two separate dates, one over the other.
If there is only a lone "1920" stamp, would one way to tell a 1920 mf'd receiver from a 1920 property stamped receiver be the regular centering and alignment of the factory rolls stamped digits v. the dates with digits that LOOK hand stamped?

That's one way. You can also look at the serial number and other characteristics of the gun to determine when it was manufactured. For example, true 1920-dated DWMs will have E/ArA4 or E/WaA4 acceptances.

Note that there are some police Lugers that were manufactured as late as 1924 that have a 1920 property stamp.
