I did notice that the crowns are on different flats, however they are the same crowns as shown on the ones with 2 crowns on the same flat, This gun was made for the European market as it is marked 'J.P. Sauer & Sohn, Suhl on the top of each barrel. Notice also it has a dolls head extension rather than a Greener cross bolt.
