Good morning.
Thank you all for your input so far.
I will check for the waa77 stamps and get back to you all.
As for the stock, it was definitely NOT re-finished. It is just in excellent shape.
The photography is making it look shiny.
The concerns that I had were two fold:
First, as Kar98kicon pointed out, the bolt parts seemed to have been re-stamped from a number 2 to a number 7 on most of the parts. But it seems to be on all of the bolt parts so I am wondering whether it could have been done at the factory.
Second, the numbers on the trigger guard and floor plate do not match (and there are no numbers on the capture screws).

I know you are going to say buy the gun and not the story however I got this rifle from a friend of mine who is the son of a WWII vet.
He was a combat photographer during the war and has many bring backs. The son assures me that his pop brought the rifle back from WWII.
I have purchased a number of items from his bring back collection and all are top notch.
I am wondering whether it was arsenal rebuilt by the Germans who added the trigger guard and floor plate?
And maybe the bolt was renumbered at the factory?
Thoughts would be appreciated.
I will look for the Waa77 marks today.
