New member but old Luger. Help identifying.

[Dohhunter]

Good day all, I've been meaning to join for awhile now as I'd love some insight as to what exactly my father has had sitting in his safe for forty years now (as with most stories, his Uncle won this in a poker game .

Some data to back up the pictures (my apologies for the iPhone files, I'd be happy to grab some clearer ones of a particular part if that would help):

1) DWM inscription only
2) Toggle knobs are knurled, no dish
3) Grip safety
4) 2 original magazines, but they appear to be unmarked as far as I can tell
5) .30
6) no stock lug
7) no marking under thumb safety
8) Barrel is approximately 4.5" from muzzle to extractor, approximately 3.75" from muzzle to front of chamber
9) two crown "N"s on left side of extractor
10) horizontal crown "N" on left side of gun/chamber (see picture)
11) as far as I know, not refinished
12) serial #55220, only matching # I see is on the rear of the gun (only a '20' as shown on picture).

Any review/comments are appreciated!

Best regards, Mike in Ontario/Canada
