1961 Ford Transmission Planetary Assembly C1AP-7A398-B

Dug this one out of an old box of parts that came out of a local warehouse.  It was wrapped in newspaper dated 1968.  Part number is hard to read but looks like C1AP-7A398-B, which at least partially decodes as 1961 Ford Galaxie (full-size Ford) with automatic transmission, transmission planetary assembly.  I have a hunch this fits an MX Cruise-O-Matic as well as the FMX, and the Ford-O-Matic, but I need to dig out the dusty books and have a closer look.  This is a Ravigneaux type gear set, named for it's inventor - Pol Ravigneaux, who patented it in 1949.
