Type 9 gearbox problem

Once again, not exige related (but Lotus, kind of!) but there is fountain of knowledge out there and it would be bonkers not to tap into it…

I have a Ford Type 9 box in the 7 - it has straight cut gears, so I expect it to be noisy… but…

MUCH quieter in 4th… noise goes away when I press the clutch in neutral, sort of ‘rattling’ on overrun…

Layshaft bearing wear?
