I've been looking for one of these rifle for quite a long time, and haven't found one I could afford. A friend of mine had Kittner 16 Bore double rifle a few years ago, and it was a smokeless rifle. I believe most 16 bore rofles were made in Germany, or Austria,and the ones found uin the USA, at least, were war souveneers, and most are still in clausets gathering dust, and in some case rust. The Double Gun Journal had an article about one, a couple of years ago, that was a real beauty. It also was German. I'm thinking about bulding one by sleeving a pair of 16 ga rifled barrels into a Pedersoli double rifle, and regulate it for lead wheel weight bullets, maybe paper patched, useing all brass cases!
