Taking a closer look at the bike and making sure of things I've discovered that the bottom bracket threads on the frame are in fact French. My apologies to anyone that was considering this frame. But I also confirmed that the threading on the derailleur hanger do accept a standard Campagnolo derailleur from about the same era.

I'm going to take the frame off the market until I find a suitable bottom bracket for it. Stay tuned if you are interested.
