Hello PRD,
I feel that the springs may be a factory design, the set-up is too similar between Fxxxrr's machine and mine to be a coincidence. I do agree with you though, another overbuilt greenfield design, the drive system should work just fine without it.
Cheers

Interesting, I shaped my springs based on one of the ones that was already there, it fitted in a way that made me think it was original so perhaps if they were factory one of mine was still original, i think i know what you mean by internal springs, my drive discs seem to move very freely from side to side and appear to have no spring pressure to return them to centre if the external springs aren't there
