Any dispute about interpreting the BofB?

Hello Ruy
100oct came from USA and British sources, props (and CSUs)were produced in GB by DH and Rotol, but both the 100oct and the prop were US innovations, prop by Hamilton Standard.

Lend/lease only began in March 1941. This is months after the BoB had ended.

Much is made of American shipments of 100 octane fuel, but.....

unfortunately I don't remember the source, but I read somewhere that a lot of the props were more than just invented by Hamilton standard, but also produced by said firm.

But I can't go further than a weak statement, since I don't have the source.

Interesting thread, indeed.

While the planning, HQ conferences and plans for "Barabarossa" are well known, AFAIK, no such things ever popped up regarding the would-be invasion of Great Britain. Am I wrong?
