I have tried to get a final answer on this one for a few years. Found this forum and joined. Need help. Has a 32" stock, 22" barrel, single large cavity behind trap on but plate and a 1902 rear sight. I see no "C" marking. What is this? Sorry for all the postings. Have not figured out how to do multiple pictures on one posting. I am a newbie here.Thanks. Ed

Update. At the advice of another collector on another forum, I measured the barrel OD. Here is what I got.
.650" @ muzzle
.652" @ front of front sight
.657" @ rear of front sight

Maybe this can help. Thanks
