It has all the S&W markings on the top of the barrel rib. Everything seems to match up well with the 3rd Revision in the big S&W book.

From the looks of the bore, it hasn't been shot in one heck of a long time. If someone was going to dump this gun because it was used in a crime, it would have ended up in the river, not the town dump. I figure someone was cleaning out an old person's house and tossed it because it looked like junk. I suppose I could have my local LE run the number after I give it back. I live quite a ways from where it was found. If it turns out stolen I'm sure he'd do the right thing.

Still would like to know value.
