100% no.
Cook Bros is not CQP. The Cook cranks are early BMX dogbone cranks without any lightening features.
I´m always surprised how high the auctions of Hutch, Titron, Cook and other stuff is sold.
BMX collector=mad; MTB collector=smart?
@biker 23: Beeing quite an addicted crank collector I am still not convinced that the CQP are as collectible as the other, more common CQP Pro-Lite titanium showed by Scant. I know at least more than one type of the "normal" ones. For example I have a right crank with a small triangle machined out of the back of the crank to clear the big ring and I have another one without that. Maybe I should make a picture.
There is a chance that some of your 4 cranks are less because of a single set showing up more than one time. I`m sure that the set sold at the flea market is the same as the one sold a few weeks later at ebay. Maybe the same as the one auctioned now.
By the way: Mine don´t show it but this one is "custom built" (whatever that means), too and it is a normal Pro-Lite Titanium:
