Sear numbers?

Can someone tell me what the numbers on the sears mean? I have a few the number 5 and 4. Thanks for the help

They are no more than production numbers to identify the tool that made them. When parts are made on multiple machines, it is common to number or identify by the particular tool to narrow down QC problems.

Ok I see. The reason i was asking it the fact that the ramp which releases the firing ping is a different shape on one that the other. I guess one could be a newer production that the other.
