A E6717 - 1983, I have it in "my registry" as Aero
G E632 - 1981, also in the registry, Professional (matt black)
4 - Professional 1980, I have something similar in my registry - if your copy has "mixed" lugs (short in front, long in back) this could be it; if "unmixed" - it's a novelty for me
G4 858 - Professional 1980, I haven't seen this one yet
