S/42 1936: Closed auction, but what about the bolt

What's up w/ this bolt body serial... bolt is at pic 43 - 51... he also accidently added two pics from another rifle.

42-36

Yes, it's odd but, looks period. This rifle was disscussed before. It was also just on g.b. and then resold. For
nice profit I'd say. If you search you will see the first time it was sold. This guy cleaned it up and took
better pictures and made some dough.. There seems to be alot of quick flips going on lately..Also
I'm glad to see the colors have been corrected on this sight..Now I can see what I'm typeing!!!

I think the bolt may be an armorers replacement, but don't see rework markings on the rifle. I guess it falls into the oddball category- it's surely not the original bolt it was built with.

S/42 bolt

By late 1935, Mauser had stamped the full SN on the bolt sleeve. This being a 1936 'h' block - the bolt sleeve should have the full 4 digit SN. My opinion, the bolt is a period replacement.
