I am trying to figure out how much gun insurance is needed on my firearms. The one I am having most trouble with is a S&W .357 Registered Revolver. I have heard quite a wide range of value at some gun shows. Has 8 3/4 barrel, King red bead fr sight,King white outline rear. Serial# 50032. Was purchased in 1949, have box and certificate signed by Harold Wesson.Would guess it at about 90% condition. Registered #1699. Any educated guesses on value would be appreciated.
