I have a 1926 44 special 6 1/2 " that was fix sighted. Sometime during its career was fitted with micro sights front and rear. I need a rear micro sight from the micro sight co. of California. Not the one dovetailed in but with the rounded front almost the width of the sight and attached with 2 small screws. It rests in a small tombstone shaped milling in the top strap.
