Just going off the V8 subject,I once got a lift over Woodhead in a Mandator of W H Martins from Brigg,loaded with billets out of Scunthorpe.It had a Fuller box,not sure if it was the 9-speed RTO9509 that was in the Marathon.The thing about it was that it improved the AV760 engine performance no end and I was suitably impressed.I wonder how many AV760 Mandators were fitted as such? I had a Mandator at the time,OKC 130M and wanted a Fuller in it asap.
I wonder what the comparison would have been like between a V8 Mandator with a 6-speed box and the AV760 Mandator with a Fuller performancewise?
