Needing help identifying K98 I recently acquired.

I have found the meaning of most of the markings on the rifle, a few I can’t seem to find any info.
These are located on the bottom side of the receiver.
What looks like a capital B inside a circle.
The stamp “0”
And the third stamp that is kind of obscure and is located between the 2 fore-mentioned stamps.
Thanks again for yall’s time.

Probably just some inspection marks from the factory that made it.

I believe all of the many spurious marks found on the underside of receivers are the personal marks of each workman who completed one of the machining processes. My dad was a tool and die maker who apprenticed under German master craftsmen at the Naval Torpedo Station, Alexandria, VA. He told me each craftsman had a unique ID stamp he applied when his task was completed.

Makes sense, thanks

My father was as well starting as a machinist while still in high school during WW2 and he also mentioned the marking of repairs, processes, etc. that he did. This was a thing already in Jersey City, NJ at least circa 1944.
