Mainly found in Continental Europe. I have a Belgian Byard 24 bore hammer double in just about mint condition. I rescued it from a local gunshop. The owner was going to have it de-activated as a wall piece. I made an offer on it and rescued it just in time. I also have a double hammer gun by G.E. Lewis of Birmingham. I can find Fiocchi ammunition and sometimes get an odd old box of something of French manufacture. Magtech make brass cases too. Not much practical use at the side of a 28 bore but fun to use something a bit different. Lagopus.....
