Very cool! This reminds me of my uncles shop when he was doing a lot of pneumatics work here in Knoxville. It was nice to be able to get Clippard stuff at cost back in the day. 
Thoroughly enjoyed reading this thread - how fantastic! Very interesting to learn about the Clippard company in this way and what a great organisation that is, so good to see that companies like this still exist, where everything is built and designed in-house, all handmade by a proud and positive workforce…we had many manufacturers like that in Great Britain once, such as our aircraft industry, names like Hawker-Siddeley and Vickers spring to mind; all of which designed and hand built their aeroplanes onsite…companies within an industry that is now sadly long gone here.
Incredibly awesome tour; I envy you guys!
They need to put a proton pack on the wall of their product time line. I’m insanely jealous they let you guys do the tour!
