The maker marked tasks books are pretty scares, I have a full digital copy of another example, contract C9310 is the only version I have seen, there may be some for other contracts, but it could also be a short period in history prior to the universal pamphlet with full tasks printed.
Jan has more, but I also have most of the Matchless stuff, and lot's of Big 4, Welbike, all of it, and some Velocette, and other weird stuff.
And also a lot of US wartime bike manuals and parts lists.
Not an instruction book as such, but perhaps of interest to this thread.
Under ‘Slimy Descents’ it mentions to raise the exhaust valve lifter when descending. I’ve never heard of this before. What’s the purpose? Surely it will just kill the engine?

John I think this has been covered in the training film and although not clear in that book, I'm sure it means, without the engine running. By selecting first gear and selective use of the valve lifter and front brake, you should be able to make it safely to the bottom. Ron
