Yeah, but I do believe they used that barrel well into model 10's. Or 64's for that matter. I've seen 64's with that tapered barrel. Which I guess is the "Standard" barrel. Eh?
From Stephen Camp's website, this is a 12-3. Not sure when that was made but obviously after 1957..... Not sure how much after... But since it's a -3, I'm thinking well after.
according to the owner of this gun, it is a model 64 (which according to wiki was introduced in 70):
I think we had another thread around here about this but I'm pretty sure 10's came with a standard tapered barrel through out much of their life. I don't know when the standard tapered barrel was discontinued though. Maybe someone can confirm that.....
It would be interesting to see just a round butt 10 with a standard 4" tapered barrel. Like that 12 above. I'm not sure I've ever seen one of those either. But I'm pretty sure I've seen square butt tapered barrel 10's. 4"ers...
