Some outward similarities but that's true for lots of SxS. Yours has intercepting sears as indicated by the pin (screw head) at the top rear of the action. Yours has the bolster for strength along the side where the barrel flats meet the action flats when the gun is closed. Style of engraving is quite different (I like yours better). You have a horn trigger guard, mine's metal.
FYI, I may have not made this clear on the other thread but there are literally thousands and thousands of older European SxS (Usually reasonably good quality) that have no name on them. It's not in any way a sign of poor quality. We typically refer to them as "Guild guns" as to join the local gunmakers guild, one usually had to demonstrate one's ability by building a gun. And they typically weren't named. However, this does not begin to account for all the "no name" guns in circulation. It's just a short hand name.
