Depends upon the age of the piece - and the caliber.
Those built in the late '20's are neat little revolvers - harder to locate in .38 Special than in .38 S&W.
They have square butts and hard-rubber grips with a stylized 'C'.
After the '30's - the round butts were common, as was .38 Special chambering - and those are 'everywhere'.
Prices will run from $125 and up - they're sort of priced like S&W Model 10's - so it all boils down to 'condition, condition, condition' and you go on from there.
If you're located near larger cities - it's quite possible you'll find ex-police revolvers in profusion - and they hung on in active service in rural areas, too.
Some are agency-marked - common if issued - others are 'clean'.
Good Luck!
