Need help identifying mark

[mrerick]

Hi, I have recently acquired an all matching "42" two digit chamber date, military proof marked Luger.

Rather than a "byf" code on the forward toggle, this pistol has a Mauser Banner.

The serial number suffix looks like:



Even though this suffix letter is listed on this site as a "g" in the photographic Tech Info section, I've been given expert opinion that this is a "y". All the "g" letters have a loop tail. This marking does not. Therefore the serial would be "xx15y".

I can't find discussion of a Mauser Banner toggle documented on a military proofed (e/135) "42" date marked receiver.

I know that toward the end of production, there was production done from the mix of parts that were on hand. Could this be one of those?

- What would the approximate production date be for this pistol?

The forward Mauser Banner toggle has this mark on it's underside:



It looks like a "R" within a "W" with a rounded shape. It's about 1.5 to 2mm in height.

- What is this mark?



Thanks - Marc
