This copper tool was from Jaguar Cars and I was told to be sure and hang on to it. Its a paperweight now.

A factory Jaguar Tool that is not even made in copper anymore, they went to steel ones so Yours is worth about $150-200 being O.E.M.

Triple SU Carbs, those are always fun to tune.

Brass. Beg your pardon. I don't know why I was thinking copper. Light metal, anyway.
The Mark VII was the most dependable (and warmest) and the E coup was starting to rust.
There was a small-shop Jag guy in Des Moines (he's past away now) who had figured out a cheap upgrade so the cars would start like a Ford or Chevy. After a thorough tuneup and carb sync, he used a Mallory distributor (Jaguar cross reference, made in USA) and Pontiac voltage regulator, backed up with a big Cadillac Delcotron alternator. My E roadster was set up this way and ran perfectly for four years without an adjustment.
