Still staying with the mid 60's and prior to Albert entering service with the RAF, in addition to learning from USAF's experiences, it would appear we also worked with our RAAF and RNZAF colleagues given their developing experience with the Hercules.

Note that the article quotes the RAF expecting to receive the
C-130E at that time.
