Barrel code on 513T

[MK111]

Derrick at least we got that cleared up. I am glad I could help.

Ramboueille it looks like yout code is "P L" which would be "P" for June and "L" for 1942.

I don't keep records on these rifles. I just collect and display all US .22 caliber Trainers. If I could only find a Winchester 1890 US marked and a Remington 511-P US marked I would have a complete collection of US Trainers. Of course there would be the Springfield (Remington) Rolling Block converted for the Navy in 1889 but there was only 100 of those.
