Dunno anything about Gambles quail - don't have them around here. However, I'd second the recommendation for a Model 42. I've owned my share of "fine" .410 doubles over the years. While they are cool - the little built-to-scale sidelocks are made like watches - those super-light, tiny guns are very hard to shoot well. Also (for some reason no one seems to talk about this) a high percentage of .410 SxS's have terrible bbl regulation problems.
A 42 has its own sort of "cool factor" and enough weight and heft to be shot well, but not so much as to lose the benefit of being a .410. I no longer use my .410 for wild birds, but I shoot plenty of pen-raised birds over my pointy dogs with it. As others have said - works just fine with #7.5 shot within 20-25 yards, even on big birds.
