Unequivocally, this is a best forum in which to post. Is the Napoleon Bonaparte scattergun a flintlock or percussion? Heinrich Ebert of Wien & Johann Andreas I(1822-1898) were both active in the 1840s and Heinrich Ebert may have hung his shingle out as early as circa 1820. And there was a Andreas Jacob Kuchenreuter active at the beginning of the 19th Century. The Kuchenreuters of Regensburg have a gunmaking dynasty that is all but unparalleled in Germany reaching back uninterrupted to the late 1600s. They had a reputation for fine tubes and I would guess the tubes of the pistols were sourced from Johann Andreas I with Heinrich Ebert being the wholesaler. The King of Austria, Bavaria along with Napoleon and Tsars are found in their order books. Dr. Dirk Gotschmann of the University of Regensburg has penned 2 books while the descendents of Johann Kuchenreuter hail from Cham in the Bavarian Forest being about 80 km East of Regensburg.
