​​​​​Sorry for belated thank you!
What I was wondering is if I could use a different axle (non-Zeus) with the cups I have? I know I need the proper width between the the axle races as well as overall length. I am slowly getting some odds and ends parts, presently have 2 bracket axles one (Galli) from the Olmo loose parts and another (Campagnolo) from the "bucket of parts" I got in Vienna. I measured the lengths and both are approx. 114mm overall. The Galli has 52mm distance between the inner edges of the bearing race surface, the Campagnolo has 50mm between same. The Olmo has a 70mm bracket shell so I assumed that the Campagnolo was for a 68mm shell regardless of threading. What I don't know is can the Campanolo axle be used with the Zeus cups? The axle seems to fit similarly to the Zeus cups as it does to the Campagnolo cup regarding the hole clearance tolerance, but will the bearings and race surfaces be compatible? Are the same size ball bearings used? I think 114mm will be a good length. I have the Zeus Cronos crankset, but if not correct for chainstay clearance I can try the Galli set, or a Campagnolo set from "the bucket".

You are correct on the "Olimpic" pedals. I never looked at the spelling closely.

I have yet to determine what type of headset and stem I need; are they French thread and dimensions? I don't know.
