Help Identifying Kar 98b

Is there a view of the left-receiver that shows the serial and receiver fireproof?

This appears to be a Simson ordnance spare receiver mated to (apparently) an S28 type barrel, which creates something inexplicable so far as known patterns go. Two different variants mated, though probably a Simson ordnance spare receiver found its way to the S28 program, or some queer mating was made in the early-mid 1930's.

This is not a factory mating probably. Though I seemingly can't view all the photographs but I suspect my internet connection may be the culprit, it is as reliable as Uncle Joe, you can always be assured of disappointment (comical if it were happening to someone else...)

@Loewe yes the photos cover every mark I was able to find. Let me know what you think once you're able to see them.

I did not see the receiver serial and fireproof, which is on the left receiver. I assume it matches in serial, but is the fireproof exact is the suffix and numeric fonts exact matches? I suspect not due to the divergent nature of the two parts... An S28 barrel is not normal for a Simson receiver, that the receiver is an ordnance spare variant, it suggests a contradiction and possible alteration to me.

No biggie if this is not something you can post here, others seem to see more than I can, but this is not "normal" - Simson and S28 production is/are quite different in origin and procedure and from what I can see there are more questions than answers.

Here is the left side of the receiver. The serial matches the barrel.

That still looks like part of the barrel. A shot of the receiver and FP should look like this.

@biggymu here you go:

Great I think that’s what Paul was after. Barrel and receiver appear to have been numbered and proofed at the same time and not just a barrel replacement. The stamps look very worn out. Interesting rifle

Yes, these pictures help, this is neither a Simson 98b, nor a S28 98b, I am not sure what it is, but it is not a combination that can be categorized. It is some sort of salvage or ordnance (depot) build; perhaps something not seen before...

For one no S28 has been recorded this high "with pictures", there is a higher S28 reported but no pictures, the nearest with pictures use a different FP (Imperial style) and obviously not using a Simson ordnance spare receiver. Perhaps this rifle is an example that can tie a date frame for the end of the S28 program?? The a$$ end of the S28 program probably ties into the start of rearmament (1932-1933). this FP is typical of 1933 era or later, not of pre-1933 production (4502/b has a Imperial/Spandau style FP, the highest S28 98b recorded with pictures), but we have little proof of this evolution, that have survived anyway, but this may be a start.

This is a weird rifle! (but legit imo) (the Simson receiver with an S28 barrel)
