For reference, I paid $1000 for this .38 spl Shooting Master, shooter condition, a little over a year ago. Shipped 1932. I think it was a fair price. 38 spl is the most common caliber.
I think I recall seeing a very high condition 38 spl, LNIB, Shooting Master go for $2500 or so last fall, maybe a coupla hundred more, at one of the auctions.
Price is very condition driven; those last few percents of condition really jack the price. And presence of the box, papers, etc., will drive it on up there, too.
