Ok, I know that in 1945 the ar code changed to dd but as far as the long step front sight vs short step and the use of barrel door rivet instead of the large screw. I have a front shroud with the long step front sight and barrel door rivet and I know the long step was only made by the arz rea code. most of these went to dfb svq coded guns (gustloff Werke of Suhl) dfb changed to svq in 1945 they used arz rea exclusively. But what about mauser? From what ive learned from other posts:
STEYR: codes bnz swj NEVER used the long step front sight because they built their own receivers and never made that change and kept the short step, but I have seen them with A Barrel gate rivet rather than screw so this would be short step with barrel gate rivet together. This was seen on swj coded Mg42 which changes from bnz in late 44
MAGET: codes cra swd NEVER used the long step front sight as grossfuss bpr like steyr never made the long step front sight change. But was a barrel door rivet ever used on a swd?
GUSTLOFF WERKE: codes dfb svq ONLY used arz rea manufactured receivers so when the long step came in all the weapons made got it and at some point started getting barrel door rivets not sure when that started.
MAUSER: codes ar dd, Now for my REAL QUESTION mauser only built a little over 4000 some guns in 1945.
I have a demilled rear receiver coded df dd serial 4652e. I know the code was 888e at the beginning of 45 and from what ive researched the highest number found was 48XXe something.
I also have a rea front shroud with long step and barrel door flat headed late war rivet. I am wanting to know if it would be proper to match them as I do not have an svq receiver.
I know mauser used a mix of grossfuss and arz rea receivers. So that means it was random some had the short step sight and some had the LONG STEP receiver RIGHT? BUT DID MAUSER EVER USE BARREL GATE RIVET RATHER THAN SCREW.
