Megan,
All the Gipsy Major's built by GM were "non-metric", as were the engines built by Curtis Wright, whether they were Imperial in AU I am not certain, but the US built engines were, I am reasonably certain, SAE.
Both my engines were metric ---- there were several studs that used to fail regularly, and from DH they were not cheap, about 5 pounds ($10)each --- in 1964, when I was earning about 20 pounds a week. I found an identical stud on a VW engine --- at about 2 shillings each. Once I fitted those VW studs, hey presto, no more breakages.
So much for "aviation quality".
Tootle pip!!
