Andrew,
I’ve gone through numerous Ford military and civilian parts lists including FMA-01 (the late-war pictorial major assemblies identification book) and I can’t find anything that resembles your part.
None of the books that I have access to show part number BBF 7222. If my understanding of Ford part numbers is correct, then BBF should refer to a right hand drive model BB truck. CMPs used BB 7222, and BBC 7222 but the Ford system was to keep the part number from the first vehicle on which the part was used.
This link claims to have a vehicle with the part number BBF 7222. While there isn’t an image of the number to confirm, the chassis does appear to be a Right hand drive model BB.

At this point my best guess is that your parts were modified, with the question being who modified them and why? Possibly a local program using available parts to provide spare shifter assemblies that could work on a Lynx in the event that the proper assemblies were exhausted?
Did they come into your possession with other Lynx parts?
An interesting mystery!
