Thanks dutz. Yeah, no question that the holes are aftermarket. I just want to fill them up with something appropriate-the damage is already done, so to speak.

There’s a Lyman sight that appears correct. 66 R-12. There are a couple listed on eBay, but I don’t know is the hole dimensions are correct-waiting for a reply.

The Redfield model number (70IT) I got from a 1943 ad listed on eBay.
