well I heard back from my guy that I am helping:
Classic Stern’s that had the “Original tombstone drop targets” are:
Cosmic Princess
Dracula
Hot Hand
Lectronamo
Magic
Memory Lane
Nugent
Stars
Stingray
Trident
Wild Fyre
Meteor
Galaxy
he believes “1980” was the changeover which was also when Stern upgraded from the MPU 100 to the MPU 200 and the 16B-3 Transformer to the much better 16B-6 Transformers.
Change of Target to the later “Hooded Version” was:
Ali
Big Game
Catacomb
Cheetah
Dragonfist
Flight 2000
Freefall
Iron Maiden
Lightning
Nine Ball
Quicksilver
Seawitch
Split Second
Stargazer
Viper.
