Boy that's a tough one. The only on-line source for H&R SN's is in relation to their Garands. The company is very old and has (with certain exceptions such as the Garands) never attracted much attention by collectors. I'd say your best bet would be to call up H&R's current owners, Marlin, and see if they can direct you to someone who has the SN database.
Those are good revolvers BTW, though their resale value is pretty limited.
nice place to find out about firearms for sale, both antique and new in box, as well as other publications they have. I have been reading and buying thru the gunlist magazine for several years though a local dealer.
It wont neccesarilay give ou the excat year born in, but can give you an idea what its worth from a dealer standpoint, and sometimes the year made is attached to a for sale firearm as well. Add it to you bookmarks.
Since H&R became New England Arms sometime back, it was most likely made in the 60's with that serial but i dunno for sure myself.
