Not all the Criteriums had the sloping forks, some had a flat fork crown.
The Criterium Triathlon I had in the early 80's had the flat fork crown whereas the one I purchased last year via eBay has the sloping fork crown.
I was under the impression that they only made the Standard Criterium in Red and the Criterium Triathlon in blue, I may be corrected though.
Either way, looks to have tidied up well.
