I believe that the Junkers patents may pre-date the F-M engines by
some years, and that licencing was carried out all over the world
prior to WW2 by Junkers. Junkers had twin-crank flat-12 diesels in
aircraft prior and during WW2.

If you take out automotive engines, most horse-power these days is
probably generated by two-stroke engines of one type or another,
especially if you take into consideration the very large marine
diesels.
