C30 LAA 12 cab

Thank you for the info,

I find the reason stated for up rating the wheel size interesting.

I would have thought that pulling a Bofors gun would have favoured lower ratios i.e. 30/60cwt diffs and smaller wheels. Improved road speed with lower transmission/engine stress would not I would have thought been an issue here, can anyone shed some more light on this?

As you know the Oxford crew run two 30cwts on 1050.16's, the C30 11 of Steve Stone and the C30 13 LAA of Keith Orpin.

The C30 11 seemed to over rev at normal road speeds around 35 mph and this was cured by fitting 15cwt diffs. On the other hand the C30 13 LAA does not seem to have the same problem, it may well have been fitted with higher ratio diffs some time in it's past.

I'll come clean my interest has been brought on by acquiring a C30 12 cab LAA from Steve recently. It's in need of full restoration and currently has gone to the back of the barn while other projects are completed.

Calling David Hayward,

David do you have any info on when the first Chev LAA's were produced?
