In 1980 FLG 150, 240 anf 90 have heelcaps. In 1981 no heelcap on my FLG 90. From 82-88 heelcaps on RLG 50 and 60 (and the goldtops), but i don?t think that the RLG 90,120 and 150 from from this period have heelcaps, but then I have only had a 1983 RLG 120- no heelcap.
It is easy to mistake a RLG 60 forh a RLG 90 from this period. Same pickups and veneer flame top, but multipiece back and heelcap on the RLG 60
