Thanks for the welcome, everyone. A little on my background, I spent a total of 11 years in the REME as a VM, for most of that time working on Centurions and Chieftains, with a 3 year spell in the middle with the Royal Artillery fixing Abbots, 432's and a few Stalwarts. When I was demobbed in 1973, I worked in Iran for nearly 5 years in support of a large export order to the Shah involving some 800 Chieftains.
Champs were dealt with in training, but were out of service by the time I joined my first Regiment.
While it was all a long time ago, if I can help in any way, I will, and if I don't know the answer, I am still in touch with a whole load of former Comrades who may.
Christmas went well with 4 generations attending and I would like to wish you all a very Happy and prosperous New Year.
