Probably not much, it is in lousy condition and there is not much call for single barrel shotguns.
I understand you felt the need to comment but clearly, your knowledge of this model and its collectable status is close to zero.
Single barrel 28 gauge shotguns bring an inordinately high amount of interest (and associated $$) if shown in the right venue. I don’t hunt upland birds as much as I used to but the gun I carry nowadays is an H&R Model 1905 in .28 gauge (choked modified) is a light as a feather and hits what it’s pointed at. I agree that 37 would fetch significant $$ if offered on the internet.
