Question on early vs late 1937 Lugers

[jamese]

Robert,
I'm sure your asking about the "S/42" series and not the code "42" series.
Code 42 series were produced starting in 1939 to replace the S/42 code.

As to the question of value, with both guns and everything being equal, my guess in 10 to 15% more for a 1937 S/42 1st ver.
