A story I heard, don't know whether it is true or not, is that just
before WW2 the British Government ordered Excel to make lots of BCAs.
Excel (or whoever) then continued to pay design royalties to
Boley/Leinen right through 1940. Ouch! Postwar, the design rights were
considered  to be spoils of war.

The US paid the German manufacturer DWM $412,520 in 1928 to settle a patent dispute over features of the Springfield rifle taken from the 1893 Mauser.

I've read but can't find where that Britain and Germany both bought 20mm aircraft cannon from Oerlikon, all with barrels made from German steel.

I was watching a program the other day about the restoration of a
Spitfire in the Shuttleworth collection IIRC and they mentioned it being
fitted with a 20mm cannon to match what the Germans used and they
mentioned it as Hispano Suiza, maybe this one

That's it, in several models and names from various manufacturers. German sources call the WW2 models "Becker".  I like the exotic name "Oerlikon", along with other unusual Swiss-German words such as Eidgenossenschaft. I spent a while researching Schwartzenegger, which can be either Swiss or Austrian. English can be interesting to research too, like the pronunciation of Cholmondeley. Although it might be my ancestry I haven't dipped a toe into Cymraeg yet.
