I came across a S&W Model 926 38 S&W 38 Short round I belive.
Serial Number AG 133230 Barrel breaks and tips up to load the cylinder

I believe this is a Harrington & Richardson product. Back in the olden days companies would mark the caliber to make buyers think it was an S & W made gun, but I'm guessing this one is probably more modern (and still not stamped with H & R).

That model number is unknown to me. We'll need pics and or more description. Is it single action, double action, hammerless? Maybe a copy?
Murphydog's popped up as I was typing mine. Now the model number sounds right, H&R.
