This lovely little tyre gauge will fit your vintage Jaguar or Rover tool box or roll perfectly. It is a generic, unlabelled gauge, marked only MADE IN ENGLAND but it's the right size and shape for a Jag or Rover kit. It's also a lot less money than the correct gauge.
This one is pretty much identical to a Dunlop 6J apart from the Dunlop logo. It's 4 1/2 inches long.
We do sell Jaguar tyre gauges, both Dunlop 6 and 6J and the style with JAGUAR and the wings logo, in case you want one of those. Contact us if you don't see one on this site, as we are constantly buying and selling vintage British automotive tools and our stock of tyre gauges changes rapidly.
