Mine, mentioned in my post above, must be AP as well. There are no words on the reels, but they came in a set with a tank, and on the bottom of the tank it says "Made in Spain."

As I said I've had no problems other than with flagrantly curly 35 mm -- so, no problems that I ascribe to the reels. That's despite the fact that they've never been cleaned with anything other than water. After each processing of film, I simply rinse them off. No scrubbing of the grooves or anything so scrupulous as that!
