He is a personal friend of mine, I recommended him to post it here because it looked off at first glance. He knows his stuff well and in the past I did buy a few items from him that I had posted here. The one thing that made me scratch my head on this particular rifle was the circled A. I've seen this in the past, and most of the time in very odd configurations, and many times based on (S/)237 coded receivers. So I thought it has a chance to be a weird build from the end of war, but maybe someone else can give better insight.
As a reminder/comparison:
I recently bought a k98 that I've been trying to identify and found and lost a thread on here talking about circle A guns. Also I recall no-one really knew why they are not proofed and where they ended up, so I figured I'd post info on mine and see if more info was found. First off, the top of...

I was given this gun by a family friend yesterday, I am told that her father brought it back.

Plus various SS rifles based on scrubbed 237 rifles posted on GB:
These markings appear on an RC K98k. What is it? (I don't know).
