Marked "EVANS LONDON," but clearly made my Holtzapffel. Wonderful hand dovetailed mahogany box with rosewood stringing and ebony knobs. Some of the rosewood stringing is missing as well as 1 1/2" of trim on the back of the box lid. The original key is not present. The tool is 100% complete and original. Much of the original Holtzapffel snarling is still intact. The original bottles of crocus and emery are still present. Evans was a contemporary of Holtzapffel and I assume he bought tools from him. Goniostat's are used to hone ornamental lathe cutters. The cutter is clamped in place and the Goniostat can achieve any compound angle.
