That's interesting Jerry.
I have references of the 60 banded rev counter in CL, Bristol and Ruddspeed engined cars.
The 50 band on mine is hand painted (albeit very neatly). I just wonder why?
The picture attached is from an AC Cars job sheet where a previous owner of AE220 is asking the factory to remove the Bristol AC badge in favour of the standard AC badge? Had he been trying to make his CL car look like a Bristol? Was the rev counter part of this masquerade?
Best wishes
