I picked up a numbers matching 1955 FWT in 243(ser# 335xxx) a couple of weeks back from a gun shop. Had a nice uncut stock with alum butt which sealed the deal for me. Had mounts and rings also. I took it home out the door for $640. I was very happy! Your right on with parts BSA. I found a gunsmith that had the correct set of swivels. I cleaned em out. He had 2 complete sets. Cost me 70 bucks for both sets.
