FYI - confirmed that is an early first year (1954 / SN# S113382) of production Highway Patrolman.
Several HP's with higher SN#'s documented/known shipped in 1954 per the S&W forum.
My estimation of the closing price on that one is based on having watched HP's regularly for years as they are one of my most favoritest S&W model.
Lots of positives with that one (1st year production, condition, all original #'s matching, the seller is a known expert, etc.).

For anyone with interest in the HP - excellent resource for all things S&W Highway Patrolman courtesy of the most best S&W resource out there.
NOTE: this thread was started in 2007 and there's lots of follow-on information throughout the thread that "needs" to be updated in the original post (i.e. SN# ranges of guns shipped in the first year of production, etc.).
