Part C. Aero Engines,

ALPHABETICALLY ARRANGED IN ORDER OF COUNTRY OF ORIGIN.

Austrian, Belgian, British, French, German, Italian, U.S.A.

Note.—So far as possible this is a complete list of all the aero engines of any importance.

Data are confined to what is now being made or actually in use; untested "show novelties" are ignored.

In the case of some engines it has for various reasons proved impossible to obtain full data in time for inclusion in this edition.

In a general way these lists are confined to aeroplane engines.
