A vacuum gage article from the 1912 Compressed Air journal.
Ashton Valve vacuum gage and vacuum gage tester.
Trade show giveaways
Often at a industry trade show, the companies displaying their products will offer customers a little token gift as a thank you or a reminder of what they have to offer. Attached is a picture of some of those giveaways I've collected. The mirror (round with safety valve in middle) is about 3" in diameter. Everything else but the dry shaver is quarter size or smaller.
Wow. That is interesting. I never thought of such items ever being made.
I recently obtained copies of some old Ashton Valve advertising circulars relating to their gages. Take a look. Circular # 109
I have seen several of the Ashton gauges in factories in Milwaukee. They really stand out. As well as a testing/setting kit.
I don't know what the steam tractor had.
