My mate supplys dial kits and other accessories for the jap import market over here also Calibra dials.
He has contacts in Japan who in turn produce the high quality products
With enough interest he may produce for the Carlton / Senator analogue clocks.
Any body got a spare set of 140 and 160 mph clocks they dont want i will pass onto him to replicate the dial fronts. I think the Calibra ones look awsome. I might have some myself, for the Carlton of course

Have a look at the web site, a different style of dial kit and they look good to!
