Thanks for the information on valve tool.

I have a Macs catalog here somewhere and will see if I can find it in there.

Mike, I don't know of the business in Melbourne, but your description brought back memories of the old pneumatic transfer system used by businesses and large supermarkets in the 60s. The ones that had a plastic or glass capsule with opening to put $$$ inside (or other things I guess), and it was then sent back and forth between checkouts and..........well, buggered if I know, but I suppose it could be the accounting dept or similar.

Ah, the memories! Wish I had those days back for many reasons.

Years later when I worked at a large hospital in Brisbane, they STILL had the same device. Never used it myself, but I believe it was to/from the pharmacy department and was in use at that time. From memory, I think that one was called a "Lampson Tube". Someone told me you could also send a softdrink can but I never saw that done. Wish I had tried it now!!!! Though I am sure you wouldn't have got it back. If you shook it up first then sent it, it would have been funny as hell, even if you weren't at the other end to see the kaos.
