My understanding of the RN pilots coming to be on 32 is that the RN "funded" 2 of the original 4 x HS125-400 series. The later 2 x 600 and 6 x 700 series were, I believe, all "RAF" buys and thus the preponderance of RAF aircrew on the Sqn. The RN chaps remained for some time after the 400 series were sold (in the early nineties), but in ever decreasing numbers. Sadly there is no longer any representation.
Real shame as they were a great bunch of guys who added yet another string of diversity to the Sqn (not to mention some new vocabulary).
