Check out the obs for 25400 (98- 43G) and 25407 (98- 45B) at:
http://www2.satellite.eu.org/ppas8/ppas98.obs

Both showed a gradual slowing.  I believe that the flash period for both is 
over 40 seconds.

Thanks for the explantion, Tony.  I had no luck searching the SeeSat-L 
archieve "latest" for the word "magnetic".  

Centaur 2 (00694) - launched in November 1963 - still tumbles with a flash 
peroid of about 45 seconds.
