Well spotted! The Record front hub has an alloy 'cone' outboard of the flange, where the Chorus version has a black steel cap. I knew that once... They're otherwise identical internally, according to the parts diagrams. Apologies for the confusion, I've updated post above.
Regarding spoke holes, indeed that was the theory, but I've seen many wheelsets with the opposite configuration, which is confusing.
