Judging by the picture, here in Ohio, that would classify as a "shooter", in fact would be a very good carry gun. . If I was selling it, I would put it on the table for $450. No box and that approx. 90% 'condition' puts it around the $375-400 market(sell) price. If it was "MINT" and the box, the price would more than 'double'.
If it was in the .22cal, you could "add" 30 % to the prices.
I'll throw out a guess. With no box and your estimate of 90% and what looks like a good bit of muzzle wear in the picture, I would put it about $500 range. The 2 1/2" blue .38SPLs are almost as available as the same gun in 4". Other opinions may vary.
