I'd guess it hasn't been running for a minimum of ten years.
Yep, I agree with you about the piston to valve, might work a bit more of a margin in there.
As far as the rest of it goes, I'm going to put it back pretty much as it was & see how it goes.
I found these in a cupboard today, 29mm smoothbores, I thought I'd find a use for them some day.
