Is a strawed Luger more valuable?

[DavidJayUden]

I'd give a slight edge to a rust blued and strawed early 1937 over the later salt blued 1937's only because you see fewer of them.
Not much significance on your 1936 vs. later 1937 guns.
Conversely, there is a certain allure with the WW2 guns and their improvements in metallurgy.
Nuthin's simple...
