Kurt, these guns were a lower priced version of the Lefever Nitro Special made by Ithaca. They had a frame made of mallable iron rather than forged steel, no checkering, they seem to hold up ok but are rather crude in workmanship. My serial list shows that they were made from 1929 to 1946 and had their own serial number range from 1 to 65779. They are similar to a 311 Stevens and I see prices that are in my opinion are ridiculous. I wouldn't give more than 200 or so for one in 12 ga and it would have to be pretty nice. I see them on the auction sites for 500 to 700; you can find NID Ithacas for that price, or decent Belgian box locks that are far better guns.
