Volkswagen GB had Islander G-AZEH for a year or so in the mid-70s; I remember seeing it "beating up" the Volkswagen Building in Purley sometime in 1975. There were some steep turns around the building and in my mind's eye they were quite low, probably something rather less than 1000'! I seem to recall it was quite a dark colour overall with VW on the fin.
The VW Building now known as Capella Court is just a few yards up the road from where I live now; Freddie Laker ran a business from there some years after Laker Airways collapsed.
The 125s were German registered.
Edit: found some pics of 'ZEH at Biggin, overall dark blue with "Express Parts Service" titles.
