If Ithaca could have installed choke tubes, when this gun was made, I am sure they would have offered it as an option. Choke tubes rescue many guns from being useless or safe queens. I have a couple doubles which previous owners have removed too much choke to have much use for my shooting. If they wall thickness remains I intend to have a couple of them have choke tubes installed, just to make give them new use. One is packed up as we speak, waiting for pickup. A British 30" 3" .410 hammer gun with cylinder and IC chokes. I'm going to have it choked with screw in chokes and if I like the result I'll restock it in a rather nice English blank sitting over my desk. The blank is nice but not exceptional blank. A gun for use, should have wood that is not too gaudy. I think it will make a killer Dove gun and a fun Sporting Clays gun.
