Check the listing for details. vintage Schauer Compression Tester, Automotive Division, pre-zip code. Condition: Used. Listed at 7.95 USD. This is a vintage guage, says it's a compression tester. It's about 2.75 inches in diameter, has a blue back but has much use wear and I don't know if or how to make it work. It is from pre-zip code era as it was from the Schauer Mfg comp. at Cincinnati 42 Ohio. The item winner is to pay for the shipping charge ebay sets there, if you get more than one thing try to use the 'add to cart' button instead of the 'buy it now' one as sometimes that way the computers can figure out the postage savings automatically....still though sometimes we just have to do it later. Anyhow, I'm just an easy going farmer so if you aren't happy with the item, no big deal, just let me know. I'd rather not ship this internationally because the cost would be horrendous, but if you need a quote let me know.
