Wonderful info.

Not to diminish your contributions in any way, but the BTV is a lot simpler (and more effective) than most people realize - especially those who never had one apart.

In the one '56 unit that I had completely apart, the rubber discs were actually in good condition, but separating from the brass valve due to sheer old age. IIRC, I re-bonded them with 3M Super Weatherstrip adhesive - now, wondering what you recommned.

Also, as you know, when the BTV vacuum piston assembly has to be disassembled, if done carefully, the gasket for the two halves (Gr. 1.359, same for all 52-56) can be reused.

As always, thanks for the great tips, Ross - keep 'em coming.
