The Boeing 737-200 then took over in early 80's followed by B737-400 in the 90's. As far as I can recall, LHR-INV continued with Viscounts until the closure of most UK and Ireland routes in about 1982 when Dan Air took on the route. Following their acquisition by BA, B737-400 were introduced until BA stopped the route altogether.
I used to travel LHR-ABZ on the way to LSI in 1974. After the Viscounts BAC 1-11s were used to ABZ, really tight seating. There was also one chaotic weekend when the Viscounts fleet was withdrawn for corrosion/fatique checks due to an accident in South America I think and Tridents were used LHR-ABZ.
