Humm. I have both the original and a strange british "classics" version, with a different generic cover for the manual and the blueprints in couchĂȘ paper.
 
There are double-sided and single-sided blueprints. The original release was single-sided while various collected release (ie, WC+addons) had the double sided version.
 
Umm, I have 4 blueprints with my WC. I think the one that I have that wasn't shown in this auction was for the Hornet.
