does luke's find add any new drawings?
I am restoring two austers now, but back when I was looking actively for pobjoys I discovered that Walter had made them under licence.
if Walter had made them they must have had a set of drawings...
after a long search I made contact with the production manager and asked whether the drawings still existed in an archive somewhere.
he said that he could remember where two old retired workers lived and he would ask them.
you'll love the answer....
allied bombers targetted the factory on one of their raids. there were two waves of bombings. the first wave dropped high explosive bombs which destroyed all the jigs and machinery. the second wave dropped incendiaries which burnt all the rest to ashes.
the little pobjoy engine was years ahead of its time in much of its thinking.
admittedly the early grease lubricated valves were 1930's thinking but the last model made was quite modern in its engineering.
if I was to build a swift I would halve the thickness of the rear spar. that would need calculating as to loads but it may be the flutter fix needed.
