Having worked for GTD for 10years and probably like a stick of rock for the old company, hearing companies riding off back of the GTD Banner grates (let alone what Ray and Graham must think) but as we all know GTD was a morphed KVA blahh........ it all keeps the GT40 banner flying, but GTD, Tornado and the likes have a provern track record which inspires confidence when in these times of watching the pennies a purchase of 40 or assosiated parts can be a sizeable outlay. Using someone elses work or rep- is one way of trying to pull in work but if you are that good be your selves and don't prefess to be something your not.
Sorry about that just got off soap box,
Confirm that there was close to 400 chassis numbers when I was still there. Quite a few stamped by yours truely. Early years circa before early '88 were patchy to wether they were put in the book or not (they would have been put in the sales record)s. During '89 Andy Bennet and Ray introduced the Chassis number book which consisted of the early numbers then latter the longer chassis number was introduced when low volume type approval was being sort. There may be more than 400 a chat with Ray would confirm.
