I believe yours is the Duhme pattern "Tipped", however this was a very common pattern produced from ca.1840 to ca.1890 by many makers throughout the US. It is aka; fiddle, fiddle tipt, fiddle tipped, french tipt etc.
Basically, it is a later version of the straight sided fiddle pattern, the "Tipped" refers to the thickened bracket form at the handle end, this is sometimes seen on the handle reverse (where it makes more sense as a wear buffer). Generically, I'd heard the pattern called "waisted fiddle" or "hourglass fiddle", both make sense and easily differentiate the pattern from the earlier straight fiddle pattern. Any of these patterns can have the "tipped" detail on front or back or not at all. Hope that makes sense to you.
