I recently acquired this 1911 receipt of payment.
I just acquired this 14"diameter pressure gage. I can't absolutely positive, but I think it's from the mid 1930s.
Another recent aquisition, an altitude gage in great condition. I can't date it as there is no serial number on the gage face. Check out the catalog page from a 1928 catalog for more information about the gage's purpose.
I recently picked up a nice chrome plated pressure gage.
Another ebay acquisition. This is a celluloid bridge counter. It would have been handed out at expositions and trade shows. I don't know a thing about playing bridge, so maybe someone can fill me in about this one.
Another old advert from the 1912 Practical Engineer
And one more.
I recently found these full page adverts from old trade journals.
I also found a pocket size caisson gage used to measure air pressure in a caisson chamber.

An old advert for the illuminated gage.
I recently picked up an Ashton Illuminated pressure gage, 14" diameter. It's missing the lighting fixture but looks like it might be an easy fix.
I recently picked up this Spanish American War (1898) trade show giveaway. Check it out.
