I have one I hope someone here could explain. I purchased this from a trustworthy man I've known for years. He says he ordered this rifle new for his friend in the late 50's. He bought it back from the friend's widow after his death and sold it to me. The gun is supposedly unaltered, and appears so to me, as it is in immaculate condition. It is a Featherweight 243, and the serial number is 113xxx. That's too early for this configuration!!! Could Winchester have had some actions laid back and used them at a later date? Can you get a letter on them like an S&W?
