38Spl's are so mild that unless this gun was never used at all I can't see a few hundred rounds through it bringing down the value at all.
FZ, like you I never thought I was a revolver sort of guy. That lasted until I was looking at the guns in the display case at the range where I've done all my shooting so far. On a whim at the end of a day I asked for a box o' .38's and a Model 19. By the end of the second cylinder I knew I was a revolver guy. The zen motions of loading and unloading and needing to reload every 6 shots plus the option for double or single action drew me in. I found that I really enjoyed the need to be more involved with the gun instead of just racking and pulling like with the semis.
Assuming it saw use in its day go get a couple of boxes of .38 Spl and try it out. Don't be surprised when you find yourself grinning like a kid with a shiny new toy and giggling while you're shooting it. These things are a whole other sort of totally different handgun experience. There's room in your shooting sessions for both styles.
Oh... I'll just add on that I'm green with envy at your luck in coming across this find. But at the same time I'm grateful that it fell into hands that can appreciate this fine bit of workmanship and history.
