Ron's 50th Anniversary frames used Cantiflex tubing and fancy lugs, and from what I understand, the Cantiflex tubeset is still an option. However, those frames did NOT come with a Diadrant-styled double-bend fork, and I'm not sure if that is an option for a Cooper frame, or what the cost would be if he did do a similar-bend fork.
Therefore, I hereby retract my previous statement that you could very likely get the exact same bike with a Cooper decal for less ... because it is, as of yet, untested.
