An interesting ML7 replica with sufficient small differences to ask  - why bother to make any changes at all ? Some features of the machine indicate that the plagiarists were supplied with a very early example from circa 1946--1948 with features including a countershaft upright with open rectangles in its face and the plain, not dished, toolpost clamp. One useful modification was the use of twin pulleys on motor and countershaft - which doubled the number of spindle speeds to 12 - and tapered gib strips on the cross and top slides.
