I have a pinned and recessed no dash 4" 66 and am curious as to what the going price for these are now. I've considered parting ways with it to fund other handgun purchases. Sadly no box or papers were included.
That M66-1 is a joy to look upon. It DOES have the no-lock stuff, plus the relatively more or less 'rare' cylinder speckle (only M66 and M66-1 had them). I would look at trying to sell for $600-750 in MY neighborhood...maybe for a bit less in yours.
