Brass frame with quick change front cone bearing for fitting different arbors, with an unusual and elaborate tailstock, on mahogany base. The only similar one I have seen is that shown in Crom Horological Shop Tools, Fig 1018. 25 cm (9 12 ins) total length, weighing 1.7 kilos.
As shown, with no extra arbors. In rather dirty but thankfully unpolished condition which, with careful cleaning, would be ideal to use or/and admire.
