Top trunnion thread pattern

[RobThomas]

Does anyone know the thread pattern on the Minor suspension legs? It is ACME?

I have some Morris MO legs to rebuild and need to cast some new trunnions in Bronze.

Thanks.

Further study shows some differences with some of the legs here. Morris MO seems to give 13/16 as the thread size (0.815 with 35 thou total lost off of the tips) and still 11 tpi. This suggests that a Minor trunnion can be oversized to fit the Morris oxford, as soon as I can find a suitable tap.
