     As far as I know production of this engine ended at the end of WWII,
and all aircraft using this type since then have relied on war-surplus
stocks. This includes large numbers of Beech 18s and DHC Beavers.
Production of engine spares was transferred to Pratt & Whitney Canada at
some stage. If you can get hold of a copy of "Power: The Pratt & Whitney
Canada Story" published by CANAV Books in 1989, you will find numerous
references to this situation.
