Below are two more pictures of a 2k range Mod. 66 no-dash gun, NIB of which I'm the original owner.
This 66 is 100% correct as shipped from the factory. It has the original stainless rear sights, stainless Baughman style front sight blade, trigger stop, etc.
Many of these guns had their sights modified with a black rear blade and a red ramp front insert installed by a competent gunsmith. I don't recall seeing any no-dash 4" 66's being delivered during the day with the Patridge blade shown on the OP's gun. Special orders were common at the time, however, so anything is possible.
Completely original no-dash guns without any modifications ARE becoming scarce and many people who are attempting to restore their modified 66's to its original condition are finding the rear sight assemblies, especially, selling at a premium price...
