Thanks Matt,
I believe you had posted these before, which I admit to downloading, and started to prepare a set of scale (modelling drawings), coupled with a set of drawings from a modelling web-site.
Having researched the subject deeper, the available kits can be converted into the early or later Mk's of the tank, all that I had missing was the "shape" of the Leyland block, as your photo's showed the AEC profile exactly.
In conclusion, I now have two sets of drawings in progress, of both types.
The intention will be to make models in 1/35th scale, even though after all the effort, v/little of the engine will be seen once all the other gubbins are in place.
One more plea, if there are some other photos of the gearbox than those already sent, they too would be of great help.
I think I am correct in saying that the clutch end / drive casting for both types is similar ??
Thanks again guys, your help is of enormous value and having myself been involved in working on cars from my early days, I take my hat off to the work you do.
The enclosed: my first proper car, my latest project and a birthday present from my wife was a day out driving a selection of military vehicles, I could'nt get the Sultan in my garage anyway!!
Regards and thanks.
George.
