I picked this up last week - I think it is a 7" Cataract Lathe, but it has a few differences. The end of the bed has Hardinge Bros. No. 2154. No other markings have been found on anything else. The tailstock is held on by a single screw through the bottom of the bed (not MT1 or MT2). The carriage has very small dials and does not rotate. Also the headstock casting (no stamps or markings)has two bulges (above the missing tray screws)and oilers on top that I have not been able to match up with other images. Obviously the brass countershaft and wood flat pulleys are homemade. Any help is appreciated. Thank you
