Havent done much with the machine for awhile. Ive had someone who knows about electricity to look at the problem and it turns out that one of the group switches (the black round ones not the red illuminated switches) is buggered. These work by turning to determine shot time and pushes in to start. Anyway by disconnecting the power to this switch everything works as intended (except the group that it governs).
Anyway I've stripped the machine down and in the process of soaking it in citric acid.
The frame has been sandblasted and powdercoated.
A couple of shots of how dirty and weathered it was:



And after powdercoating:
