Late ‘75 and into ‘76 was tripping out of Orkney home to Teesside and using AirUK from ABZ - some trips were F27 via NCL to MME and a couple were Heralds(?) via MAN to LBA
PZU - Out of Africa (Retired)
It was most probably with Air Anglia as AirUK did not come into existence until 1979 I believe. If memory serves me correctly, Air Anglia had a lone Herald but didn't start operating it until 1977.
