Sorry Folks but my SCSW is buried at the moment due to a recent move.
Anyone know of any factory installation of CCH hammer and trigger for early Model 66s?
I've seen a few over the years, almost all with TT/TH and I'm about to purchase an otherwise sweet example so equipped.
Occam's Razor would suggest these are post factory "upgrades " to the TT/TH configuration, but S&W has pulled part changes in small batches in other instances, like during model changes.
AFAIK, all original 66 ND examples I have seen had either stainless or flash chromed hammer and trigger. Not saying they couldn't have case hardened H&T, but I've never encountered them.
