Hi folks
I have a Q on these Campy headsets. These 3 images are of the same bike, and presumably of the same "Record" headset.


These 2 images are of a different bike. As you'll see, the lower half is clearly not Campy, nor is it a match with the upper half. The upper half, however - looks like the lower half of the headset above (image 3).

So labeling all the images 1-5, 3 seems to be a match with 4 (?). They are on different bikes so they aren't together. I didn't ever expect the headset in images 1-3 are not together, but with this 2nd bike, now I'm wondering.
So Qs: Is 1-3 together or is it a mismatch? What do I have in image 4 and 5? If 1-3 is a mismatch, does 3 go with 4??
Thanks in advance.
