G33/40 help sought

Since there seems to be an issue with someone renumbering G33/40 bolts, another collector has shown me these photos to study correct details of numbering, proofs, font, placement, etc..

Could anyone please comment in wording to explain what is shown in these pictures so I can fully grasp what makes this an entirely correct example? Is it only the serial number fonts, or other factors? And are there any details about this rifle that is particular to a "dot 1941" versus a 1940 or 1942?

Thank you to any and all who are willing to help us learn.

the issue isn't just with 33/40 bolts its all bolts. Due to the fact of a x2 at least price increase in price. This is a killer example of an earlier example.
the earlier rifles are so much nicer with the solid wood and lots of proof marks. The 42 dated rifles lost all that. Less appealing because. IMHO

very nice rifle you posted !!!!!
