Hi and thanks for your reply.
Thats one of the problems that model number refers to a screw type compressor and its very definatly a 2 cylinder 2 stage reciprocating pump, not a screw type
So i recently obtained this great old piece of kit and would like to get it working properly firstly though having trouble identifying it so if any one can help i would be much obliged,
its definately Champion it says so all over it lol but the model number and serial on the data plate dont seem...
