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.
I recently obtained copies of some old Ashton Valve advertising circulars relating to their gages. Take a look. Circular # 109 C ircular 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.
I picked up an Ashton wheel press recording gage on ebay. It needs a couple of parts but I think I can find them. 70 pounds!
After seeing the many testing devices, I wonder how they calibrate those? Is there a tester for the testers?
Good question. See the attached below. My assumption has always been that the test gauges would be checked constantly to insure accuracy. An assumption! This page is from an 1896 catalog. It may help to answer the question.
I recently purchased this ink blotter circa 1898 trade show giveaway from the eaway of an ink blotter relating to the Spanish American war.
