It gets confusing. CQP (Cooks Quality Products) are products made by the Cook Brothers, after they sold CBR (Cook Bros Racing) to jack Witmer.
There is more info on the history on the MOMBAT link.
From the look of Gil-M's cranks you linked to (particularly the spider/ Circlip) it looks certain that yours are CQP.
Now to the question if a 130 mm spindle (Klein design) would work on a Klein Attitude 92.
As the present 125 mm is to short for the CQP's.
The Klein tech manual sais Cook 1992 should use 130x29.
Guess 130x17 (or 25) must be ok aswell, or?
