Smith&Wesson still has complete rear sight assemblies available through their parts catalog and Brownell's lists ten different assemblies for the M66, depending on the height of the sight blade.
I have emailed and called s&w already.
They told me they did no longer handle model 66-2.
However, If I do not get one from this forum, I will try brownells.
I have a rear sight for the model 66-1, stainless steel. It came off my 66-1 when I replace it with blue sights. Has white outline blade. front screw missing as well as rear stud. but rear adjusting screw in place. have pics but on my home computer. I will be home tomorrow night if any interest.

Do you still have some 66-2 rear assemblies? My grandfather replaced his rear sight assembly with a scope for hunting and he passed away a good 15 years ago. I am just recently trying to find the rear sight assembly and am interested. Any info is greatly appreciated. Thanks
