Bob was right on! It is a Chrysler product. The P15 (same as car model
number) in the engine number identifies it as a 1946-49 Plymouth engine.
The engine numbers ran continuously '46-mid'49, so while I can't name a
specific year I'll guess 1949. A Plymouth club might be able to supply
more details. Wow, talk about strange engine swaps!
