I have bought some spares for my big 4 and there is an oil pressure tell tale with it.i wou.d likje to trade it for big 4 parts. I am looping for a gearbox speedo.drive rear,smiths speedo i dont know the correct onze my big 4 is from 1953. Or a main stand .
as the tightened nut did not really solved the problem, i have added a self-made leather seal on top of the original felt seal today. there was no significant oil pouring out of the telltale after a 20km ride this afternoon. apparently the old school leather seal works.
