Hatch prop transition

Does anyone here know when the transition was made from the stick-style prop to the scissor on the tailgate? My FHC, built on September 1, 1965, has the old-style stick with a square opening in the chromed receiver, but I’ve seen earlier 4.2s with the scissor. I assume mine to be original (judging from the corrosion).

The change for LHD FHC was at car number 1E.31413 (Spare Parts Bulletin P.152)

Odd. Mine is 272 cars later. I wonder if Coventry had some old props lying about and emptied the spare parts bin.

FWIW, mine is 30148 and has the stick type.
