I can vouch for the new cylinders working well, but my triangular one had a good diaphragm so i had the bore re-sleeved in stainless and i re-built the rest, works really well as i bench tested it overnight for holding pressure, but strange thing is as rare as a decent one is nobody wants to pay a decent price, so it is now just an ornament.

Thanx for the advice - may well get a NEW one when I've tracked down a r/hand calliper.

I should have a disc
