I know right! The weird thing is that with the common 23x700c race tyres the BB spindle would sit only 4mm higher, at exactly 10" / 25,4 mm!

IOW: She knew what she was doing....Are you sure this is the proper OEM fork?
I just feel there is more to this somewhere.
What is this '"80's road frame you found for cheap?"
I don't think I mentioned anything about brakes or forks so I struggle to follow you here... In terms of brake reach, it's pretty reasonable at 50mm with the said 650B wheels, and I'm confident this is the original fork for this frame. It's a mid-80's low end Rossin "Infinity" road bike in the smallest size, 50cm. I've only just run a mockup configuration, and as of now I don't have a good pic of the bare frameset.
As for the other candidate, it looks like this
With the little info I have (while waiting for the seller to respond to my questions) I tried to make a geometry model, had to guess-timate most of the measurements but here goes:
So what I know is head tube 10 cm; seat tube top to center 40,5 cm; toptube 47,5 cm (which for this model I assumed is measured from the actual, sloped toptube, not the virtual horizontal line which would close in to 50 cm, but OOH I have long arms&torso in relation to my lower half)
322mm radius is for 559 wheels with inflated 42mm tires.
