Curl:
Thanks heaps for the pics. That MacNaughton is pretty wild, I remember seeing a photo of Bill Feldstein's MacNaughton, a .600 I think, with short ribs and a muzzle-band. Weird.

Guys: I don't care much for the folding peep on the top-lever spindle, too hard to make for starters, and too much of a 'gadget' for my taste. Bit like a tang-peep, always in the way.

Also, the 'wedding ring' style of ghost-ring sight, like on the MacNaughton, always looks fragile to me, and a bit dangerous: I think it would hurt a lot jammed into your thigh after a fall.

I have knocked up a sketch of my intentions for a ghost-ring sight on the future 12-bore rifle, apologies for my manifest lack of artistic talent, but hopefully you get the idea! It is counter-bored from the muzzle-end, and would be matched with a standard gold-bead caterpillar front sight.

If anyone has any other examples of this style of sight on a double, please don't be shy!
