This old lathe came to me in a trade at the February 2, 2003, CRAFTS of New Jersey tailgating.  It caught my eye because it's nearly complete, and because the parts are all in good condition.  It swings about seven-and-a-half inches; there's a four-inch swing over the cross slide.  Someone had invested quite a bit of effort in replacing some key parts: the crossfeed screws and their nuts (both the longitudinal and the transverse), the tailstock spindle & its feed screw, particularly.  What's missing are the countershaft and the bed.  The main parts were meant to be clamped to the bed with wing nuts and washers (two sets of which were included) that bore on the underside of the bed.  That means the bed had to have a clear slot down the middle so that the crossfeed saddle and tailstock could be placed at will.  What's holding them in alignment in the images is a pair of steel rods.  The longitudinal feed slide only swings about thirty degrees off the axis of the workpiece; it's shown below at one of the maximum positions.  The bearing areas of the crossfeed assembly and the tailstock on the bed are tiny; neither component was intended to glide accurately along the ways.  There is only one lathe in Kenneth L. Cope's book, American Lathe Builders: 1810-1910, that has back gears and a stationary cross slide resting on  double-Vee shears.  That one was made by Amor & Bowker of New York City about 1880, but it has a more modern back-gear mechanism.
