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.
Restored chronometric speedometer for MG VA or SA in excellent condition. There is a small chip in the rim of the glass but otherwise it's perfect. Trip reset works.
