The pictures below show different frame and yoke assembly numbers for a 25-2 vintage 1979-80. Has anyone else seen this?

Were revolvers shipped with mismatched assembly numbers or does this always indicate a later change?

Were assembly numbers used by S&W sequenced in order by frame size? These assembly numbers are exactly 700 numbers off. Could that indicate factory assembly at the same time?

Could the B13 be an inspector's mark verifying the building of a mismatch or be coincidentally found on both pieces matched up by someone after shipment?

Thanks for any info.

The assembly numbers should be the same as the side plate and yoke are fitted to the frame at the same time. B13 is a fitter or inspector stamp.

While the numbers should match, and the sideplate too, I would think with the numbers exactly 1000 apart that this is a simple stamping error. Similar to the sometimes seen serial numbers in the yoke cut and butt which sometimes are different by one mis-matched digit! Since they are on the same piece of steel, the frame, no one questions that something had been replaced! Or the M29 marked M28, or 57, or 58 etc, which have all been posted on the forum in the past.

If the numbers didn't match at all then it would be obvious there had been some parts swapping.

Appreciate the info.

I suspect that the yoke was changed out after shipment. As long as it works, it's good.
