Headset just has a spacer, colour coded, the idea is the frame is smaller to make it stiffer, the seat tube extends beyond the top tube and the spacer in the headset makes it the correct size. Colour coding of the stems was just a family thing! It's made from Reynolds 653 by the way, with 753 rear triangle and Colunbus aero forks.
Here's my TT bike with 24 inch front wheel from the mid 80's, it had a campag disc too, I wonder where this one is now?
I'll try and dig out some pics of yours in action too.
