Thanks 'Protruck', it'll need plenty of work, I'm looking forward to the challenge.
Thanks for the info about the gearbox pump, 'rbrtcrowther' I'll make sure that I check this out. I read in a previous thread that the gearbox pump doesn't work between R and 1, even the previous owner didn't know about that and he had two explorers. I've got no other big toys, I've had plenty of Land Rovers and I look after a traction engine, but the Scammell is all new to me really. She's got a RR eagle 220 under the bonnet.
