It sure wouldn't hurt for the op to email Lew Horton to see if it's one of theirs. In the SCSW there was no mention of a 3" barrel Classic Hunter. Although, as thorough as the SCSW is, there are a few things missed. We are talking about S&W!!![]()
I tried that about 8 years ago about my 3"610 and I'm still waiting for an answer. Later I emailed S&W about something unrelated and as a side note to the answer he mentioned he noticed by the serial# it is a Lew Horton.
