.44 Calibre 1873 Peacemaker with a black powder percussion cylinder (Any .44 BP revolver slot).

Looks identical to the original but obviously UK legal.

Heres the Colt original for comparison.

The cylinder is removed for loading using the stand you can see in the first pic which is of course included, this pistol is immaculate and as very few were imported here (Uberti ceased production before the cartridge pistol ban) its quite rare.

£275, you'll be very lucky to find another
