The Davenport is a single, I think he's just asking about doubles. Another maker of singles was Shattuck by the way.

The ones Bill mentions are all "gun makers" not "gun companies".

I've hunted with 8 and 4 gauge guns over in the UK. It's an interesting experience, some of the best times I've had waterfowling. Killed a mallard drake at about 70 yards with a Holland & Holland double 4 bore, what a day.
