Curt,

I'm not sure what you are asking. If you want to know which M1892 parts actually had serial numbers, that would include the following:

1) The M1892 bolt handles were serialized to the rifle from SN: 31-400

2) The magazine gate (door) had serial numbers until around SN: 11,000

3) The cartridge carrier was also serialized until around SN: 11,000

4) The follower was serialized until SN: 670

5) The side plate was "intermittently" serialized until SN: 11,000

If you are asking something different, can you let us know?

Thanks and hope this helps. This is one area that Poyer's reference book is pretty useful.
