1920 Commercial model markings

[Lugerdoc]

Jukka, The true Weimar commericals with commerical C/N proofing would have matching serial numbers in the commerical style, when they left the factory and any previous military date, proofing and serialization would have been removed. Weimar reworks by Simson et al, may still have military serialization and characteristic, but generally have additional proofing. Tom
