Ah Greg, I'd forgotten about yours.
The two I mentioned were Dave's and Brent's both with OTC.
Unusually the PAW plain bearing bushed blue headed 1.5cc diesel is considerably heavier than either it's twin ball bearing brother or the Oliver Cub.
That might explain your contrary result.
I do have a hi res scan of the plan (1.1 Meg). It just needs rescaling.
