Here's my small track. Better than average guns would command prices higher than the average shown in the track.

Smith & Wesson 36 1-7/8 in Bbl Revolver in .38 Spl. Bluebook of Gun Values (33nd Edition) indicates between $360 in 95% condition and $535 in 100% condition for this gun. I have 63 recorded prices for this model gun from $250 to $600 over a period of 4 Yrs 8 Mos ending September 6, 2012. The average price as of that date was $396. No refurbs, no refinishes, regular sights. All represented as 95% or better. No distinction for import location or engineering revision, if any, no special editions, no distinctions for box, papers, tools. Current or last MSRP is $822.
