Very daft Idea but the screws look identical the the grease plug screws on the hub outers but with a bored out centre.

OK - I now seem to have something that should work.
The spring I found appears to be OK - on two cars the assembly is OK, but on a third a little weak. I'm still awaiting another sample.
The cost works out at £12.50 for a pusher rod, the screw-in part and a spring which I'll describe as "One set internal parts gas/ignition lever".
I have 12 sets available with more in the pipeline; first orders are limited to two sets per person.
The machinist fits the job in between others to keep the cost down.
I need to separate this from my normal business, so here's how to pay:

I think I've finally found a spring of the right size and strength and, if spec it should be OK. The originals had a relatively thick wire about 0.9mm in diameter but the spring was only 3 mm in diameter. From the samples now tested the only way of being sure of enough power was to wind a 4mm diameter spring inside one of 5 mm. A lot of fuss for a simple task!
Note: the tiny springs sold by what seems to be the UK's largest supplier are made - in India.

Update: instead of each spring costing around £2.50, the ones now found are only around 40p each hence the cost is now reduced to £10, delivered, for the three parts. They should now be available in early November.
