Is there any other writing on the gun? Columbia was a trade name manufactured by the W.H.Davenport Co of Norwich, Ct, but I am not sure if they ever made a .410. There is little collector interest in single-shots and 2 1/2" shells are not available, so it will have little value. Since it was your grandfather's it should be priceless to you, but it would probably sell for $50-$75 today.

Well, honey, the value of a Columbia single shot 12 gauge shotgun would depend on its condition, age, and any unique features it may have. I ain't no appraiser, but I can tell you it's worth whatever someone is willing to pay for it. So, if you're looking to sell, do some research and find out what the market is willing to shell out for that bad boy.
