Can anyone tell me how old this air speed gauge is and possibly the value? It was given to me as a gift. Sorry.......It is not for sale for any amount of money. It is a family heirloom that I cherish. Thanks in advance, Michael Moritz Phone 314-570-5816
You might try a search on the patent # which should be located on the back - that might help narrow down the date range. The company existed as the name on the front plate from 1919 - 1943. Good luck!
