Is yours a dash one?
A Model 66 with a 4K serial prefix my guess is a 4" with a SS rear site no red ramp insert ?
Pics, pics, pics please!!
I'm an old fart,,,, i'll have to go buy a camera
Yep! it is all that. I was just wondering why the serial no. was so different , my guess is that they batch the numbers to the years made.
