I just wanted to report back having got a pair of tumbler gears from Home Workshop and Machinery. Having compared the NOS Myford ones they are certainly different in the grain of the material isn't radial. I fitted them and all I can say is that they just work. No tight depthing of the gears, it runs nice and smooth.

The fake Myford ones which fell apart didn't depth correctly. Having measured the 28 tooth wheel, it was 0.3mm bigger across the wheel which wouldn't help matters.

So I guess you just make sure the parts you get are really original Myford. Hard when you are faced with Myford branded.

Anyway, problem solved so thanks for all the pointers.

Social distancing in the workshop gave me the opportunity to make a batch of these gears.
