The Dunlop Model 6 tire gauge was a popular motoring accessory in England in the 1950s through 1970s. It was similar to the Model 6J, which was used in earlier Jaguar tool kits (the 6J did not have a tire valve extractor, which screwed into the end of the indicator rod) and will fit in a Jaguar kit exactly. The Model 6 was original equipment on Rovers and many other cars. This one is in unused original condition overall, although the original metal tube is pretty battered! The gauge itself is excellent, and hard to find in this condition.The tire valve extractor is in the end of the indicator rod, and the pocket clip is in place.
