Great find! Glad you got it. They were a inexpensive rifle but very well made.
I wouldn't shoot it until it's 75th birthday!!! Just 2 years away. It is worth a little more than what you paid for it I know that for sure!!
I have never owned a 341. I have owned several 512's, 510 & 511s. A couple of 513-T's and a 513-S and a couple of 521-T's. All great shooters for what they are. That gun was made to last a lifetime if taken care of. Unfortunately most weren't.
If you want to sell it think of me!
