I picked up a 4 digit Single-Six, kind of a beater, but I can't pass these up


Correct sights & ejector rod length. Not converted. Polished grip frame and wrong grips.
Round loading gate!?!?
I have read somewhere that some folks didn't like the flat gate and replaced it with a newer
round one. Or with the other issues is this a Frankenstein gun, parts from more than one gun??
OR....should I get a Ruger letter and see when this one was shipped, maybe a parts bin gun
released at a later date?
All thoughts and comments welcome.
Enlighten me team ROCS......
Cheers,
JAY
