That is one I am looking for and you don't see them very often. Great find, being in the right place at the right time sure is nice. I like the grips a lot ! I love the finger groove wooden grips. They just feel right to me. Got a no dash 66 SS sight and a -1 both 4" and a 2.5 inch no dash, but no 3". I was under the impression the 3 inchers were -3 and a special run made in 1988 or so.
