This is an original aftermarket oil sight gauge for a Model T Ford. It replaces the two taps on the sump to check the oil level. Typically a plug was fitted where the upper tap was, and this gauge was connected to the lower tap fitting, with the lower tap than attached to this gauge. The height of the gauge meant that is was easy to see the oil ..
This gauge was originally fitted to a Fiat and is probably from the late 1920's or early 1930's. At that time a number of car makers used the sophisticated Nivex system.
This gauge is 50mm in diameter. The glass is chipped but otherwise it is believed to be in good condition.
