Ok, I've looked at the stamped date code (41 in a rectangle), which apparently means made in 1988, The cranks are not as flat as those in besams velobase link, mine have a more pronounced profile around the screw holes, so I still think these are chorus cranks (there wasn't 2 nd gen Athena in 1988) but the dustcaps are from an Athena c'set. Happy to sell them without those confusing dustcaps!
