Here's another one, MX Leader in size 59 and FNP (Collstrop) paint, serial H F7561.





Based on documentation I would say this is:

- MX Leader v. 4
- Built in (mid?) 1995

Is there any other significance to this frame? I ask because in your list you have F7651. Also, there is a name on the frame however I have been unable to attach it to any former racer.
On a side note, I bought this frame for a friend and now I want it for myself. So, I am in search for another MX Leader in size 59 (hint Jacek).

Edit 1: I have disassembled the fork, there's a card on it:



And the more I looked at it the more I discerned:

F7561
MX 60

I couldn't see any other info. So, I take it this is size 60 after all...

Edit 2: Modern cameras and graphics software are amazing, I have found the color code (FNP):




No surprises.
