If the pics are not good enough please let me know.

what I am really trying to find out is, are these barrels 2 and 3/4 inch ?????? and what are the barrels ckoked for....?

the number at the back in the circle is 270 I think.

the other question is where are the proof marks for a Lefever nitro special ........there is nothing on the flats.....??

let me know if you need more.

thanks in advance.
