I have a 1985 336 JM stamped 30-30 that when I took apart I found this inscribed on bolt. Any ideas? I thought maybe someone did it to identify if it was stolen. 20140324_171507.jpg

All the bolts I have seen have had some sort of number scribed on it. Although, your picture shows the sloppiest markings I have seen.

should be the last four digits of the rifles serial number... they looked to be scribed by hand with an electric pencil... IIRC, used to make sure the bolt and receiver stay together through final assembly... others with more knowledge, please correct me if I am off base here.

They are the last 3 digits of the rifle's serial number. (And a letter, which I don't know what it means)

There are many like it, but these ones are mine... 012 from a 1981 336C with an extra "B" and 154 from a 2000 336M with an extra "D".

Bolts were hand-fitted for proper headspace; then numbered to the gun frame so that the correct bolt was reinstalled during final assembly after all parts were finished. That flat surface on the bolt is where the serial number, or a partial serial number is marked on the early Marlins I have disassembled; and like a previous poster noted, I haven't seen a marking done that sloppily.

Here you can see the corresponding letter on the receiver, a "B" on the 81 336C and a "D" on the 2000 336M:

There are no scribblings or engraving on my Remlin, with that I surmise that Remington doesn't give a flip what goes with which.

I have seen it on at least one of mine and was not sure what it was but did not pay attention to the numbers. I will check next time I clean mine to see if they match the serial numbers. Sure enough I would have never noticed. I had my 1953 30-30 on the table and checked it. It is an A.

Without taking the bolt out it does not look like my 1952 has it on the bolt. I am guessing it is worn off like much of the bluing. It could have been replaced as well. I know my Glenfield has the markings as I saw them last time I was cleaning it.
