Hi.I have an Oxford RT 110 that’s been sitting around for twenty plus years undercover and out in the open. I have tried to protect it from direct rain etc. I recently opened it to discover the internal mechanism covered in a thick oily dark brown deposit. The oil is also dark brown but at the right level to make me think the is no water in it. It also does NOT look like an oil water emulation. I have cleaned off the deposits from the coil, transformer, contacts etc(. Being careful to protect myself and dispose of the waste safely). And specifically cleaned the contacts back to bright metal. Now back together but to be certain I would like a opinion on the risks and chances of it working and if the oil is a problem when not clear. I don’t really have the money to pay the 120/40 pounds for 3.75gallons of new oil it states it needs on the cover. As Lawrence Olivier asks in Marathon Man,.......... ‘Is it safe’....... many thanks for any advice. I did not take a pic after cleaning.
