Old 9" advertising thermometer Lehmann Machine glass

This is a very nice vintage advertising thermometer with a metal housing and curved glass front.The thermometer is 9" in diameter and the housing is 1" deep. The thermometer is advertising the Hydratrol lathe made by Lehmann Machine Co. St.Louis ,Mo.The picture is bright and vivid and looks like it is heavy cardboard.The cardboard has a few waves in it but doesn't effect the needle from working, which looks like it is working. I did not try to take the back cover off.T is a little surface rust on one side of the housing- but not bad.This has been hanging in a garage for a long time.T is no indication of the maker of the thermometer that i can see , but it is made very well. Buyer pays 7.50 shipping.I accept MONEY ORDER ONLY.Please see my other auctions for more neat stuff.Thanks.
