I sprang for one of the Bonehills in the recent Gavin Gardner auction and I’m very taken with it

It got me wondering: why don’t you see more cylinders in the butt? (Are there other examples?). As a sort of Edwardian/inter war bullpup. It does make for nice and firearm like lines.

I suppose there is a limit to how long or wide a thing you can stick in your butt, so it’s possible you couldn’t get to the uk limit, but power isn’t everything.

The recoil wouldn’t quite be in line with the bore which could effect accuracy, but I wouldn’t think the misalignment would be much. (Far less than a pistol with the spring in the grip). And anyway so long as it behaved predictably the end result should be accurate enough

So why was the design not replicated?
