I have just arranged to buy this nice little shaping machine.
It was described to me as a pre-production prototype for the English Acorn 7" (Atlas in the USA). It does have a few unusual features including a proper clutch and gearbox for the speed change, and also a pumped lubrication system with an oil sump in the base. It has been "show" finished with all the handles having been chrome plated etc. The main body is a fabrication, but the base and ram etc are castings. It is very similar to the Atlas in many respects but obviously not the same.
I have never seen one just like it before, and would be interested to find out a bit of its history if possible.
