Does anyone know where I can obtain a Millett or other aftermarket replacement sight for an early (SN 68XXX) Model 15-3 revolver from Dan Wesson? My late father left my brother the Pistol Pac he bought new in about 1974 or so but in spite of lack of much use, the rear sight (which was at the time produced in-house by Wesson) is pretty sloppy. He'd like to replace it. TIA for any assistance.
