A google search for Servex garage equipment tells me that the co made a lot of garage hoists, hydraulic presses, wheel aligners etc and had a history going back to the 1930's. There is an un trusted Trove link to 1950's advertisements but I have not gone there yet.
Seems the last of the co was merged with other groups in the '80's and one division still supplies spares for wheel aligners.
I certainly recall most garages had hoists powered by a Servex compressor atop a vertical air receiver from 1940's to '70's. Some of those old designs were made unchanged for many years, so finding dates could be difficult.
My 2 cents worth. Combustor.
