I need to swap out the bar /stem combo on my Merckx and I am contemplating whether to replace the Campy levers below. The entire bike is D/A 7400 / 7402 with the exception of these Campy levers. 2 questions for the forum -

1. Any idea of what Campy levers these are?
2. Would you swap them out (if you were me) for a period correct Shimano set? I have a set of Shimano 600's, and it seems like non areo 7400's are not to hard to find. While period correct would likely be areo, this is my Eroica bike and I want to keep it non areo.

I am more about function than being a purist, but welcome the input.
