Hi Bill
I have a old BEN Patents Ltd Compressor unit, It has a Century RS P4 motor driving it (which needs attention at the moment). I can’t seem to find any info on it online but I do have a couple of pics for you. The second pic is the motor with the back off.



The last pic is a unit which closely resembles the compressor unit on my setup.

I wish to strip the driving pulley, l already removed the key locking bolt and tackled the front of the pulley.
