That's all brilliant and very useful info thanks. Mine does have maxon pickups I have managed to clean up and lacquer the bridge today. It's not perfect but it's a start. I also managed to get 3 grub screws out of the saddles with heat an penetrating fluid but sadly snapped the last one leaving nothing to grip. I also rewired the electrics and it's working to a point but without strings or a nut I had to resort to using an acoustic string and les Paul nut not ideal really. I could really do with a wiring diagram as I'd like to renew all the wiring and pots, I used a couple of 500k ones and a used 250k to test. Parts needed now are pots, 1 saddle, Jack plate, nut and some strings and then the rest us refinishing. I have refinished quite a few guitars but all in dye, oil, wax or paint. I think this may have been shellac but can't find out for sure. Anyway here is some progress so far:
