Thank you all for the comprehensive advice.
I had noted that EP oils were not to be used – thanks for the confirmation.
I also appreciate the channelling problems that too high a viscosity can cause.
Being a bit uncertain about the gearboxes internal condition, think I will start with 50w straight oil, observe for leaks and move towards 140w should it be necessary.

Ted: you said that straight S.A.E. 50 was good enough when they were first made ….. I cannot find any lubricant info in any of the books I have.
Is this listed somewhere or just that you happen top know this fact?
