What is the value of a Harrington and Richardson four ten Handy Gun?

Answer

Values range from $75 in Poor condition to $400 in Excellent condition. However, unless it has a barrel over 18 inches and an overall length of 26 inches or more, it is classified as a short-barrelled shotgun by the BATF and possession in the US is illegal unless it was properly registered in 1934 or during an amnesty period in 1968. If it was registered but the papers have been lost, the BATF will not look for their copy. Possession could result in a fine up to a quarter million dollars and/or 25 years in a federal penitentiary.

I've seen these guns sell for $700-$800 at gun shows in the west. They seem to be very rare and it appears they are quite collectable. I do know they sold off of pictures with special arrangements for the transfer. I would think that the ATF have a lot better things to do than worry about single shot .410 collector hardware.
