Interesting. I inspected the 66 no-dash's hammer and can't see an S. Do you know if the S is visible without disassembling the gun?
Several years ago, Wikipedia stated stainless hammers and triggers were used initially, but were changed in later production due to wear issues. However, that statement does not exist in the current Model 19 and variants page.
It's been about 30 years since my last foray into studying the innards of Model 66s and their siblings. I remember for sure that there was an "S" somewhere on my Hammer and think there was one on the trigger as well, but at the time I was shuffling parts to "blueprint" my 66 ND, so what part came from where was of no interest back then... I was building the slickest possible "stock gun" that I could. After three plus decades and replacing a set of parts or two, it's still the slickest Model 66 in captivity, but it's now morphed into my Model 616 in 327 Fed Mag.
Anyway, your question about the location of the S on the stainless hammer eludes me, but I am certain it's there somewhere if you have a stainless hammer and is absent on the flash chromed parts.
