I have recently been fortunate to acquire a total of 3 factory model 66s' with 3 inch barrels. Believe me ,they did not come easily. Gun shows, gun shops, gun broker, the forum classifieds. I spend an inordinate amount of my free time searching, and have traded and paid dearly to acquire these.
My discussion today is on the changes in the model 66 engineering, and the 66-5 in particular.
This 66-5 is a factory 3.25 in. barrel. product code 102720. Hi Viz sight, V notch rear. All m.i.m. internals ,but thank heaven no lock.
I've only seen a couple of 66-5s and they have all been heavy barrels, like the model 65. These included this 3.25" and a 4" round butt.
There is no mention under engineering changes about the barrels in the S.C.S.W.3.
These pictures are of my 66-2, prod. code 102712, spec. ord. # 5108 made April 1985. Ser. prefix ,AFKxxxx.
The 66-4 ,RSR, 3" glass bead finish, magna ported. prod. code 102715, made 1996. The serial # prefix is CATxxxx which I think is kind of cool.
And the stocking dealer special or R.S.R. gun. I'm not sure which ,as they both have the same product code. Serial prefix is CFBxxxx and the fired case date is February 1st. 2002. One of the last pre-lock guns I've ever seen.
Your pictures and thoughts welcome,
