Hi Micdrow
Can i ask you to check if you have the same document, only for the Merlin 21 engine, and a few others?
the front looks like the 8, 9 and 16's only blue

They do have it at the flying clothing company, but they want a whoopin 85£ for it (original paper manual). I could buy it scan it and then start dishing it out for 5-10£ and then hand it to a museum, but that would be my last resort
