Some say payment was made by sending Watson-Watt to the US in 1941.

Not me.

An awful lot of American civilians sent their personal firearms to England in good faith, for use by other civilians.

After the war, the British government, afraid of allowing its subjects to be armed, confiscated them and destroyed them.

The Americans were TSOL.

I don't consider a visiting RADAR pioneer to have anything to do with it whatsoever. If I steal your wallet and write myself a few checks, I can't tell the court that it's OK, because I planted some bushes in front of your house and painted your garage.

OK, I didn't know about personal stuff being sent, was that promoted as a loan or what ? I was referring to Roosevelt's "lend-lease". Watson-Watt's work pioneered microwave radar with all that implied for ASW etc.

Regarding the personal firearms, from a practical point of view how would people realistically expect to get their guns back after a war ?
