Hello Bob,
Here is an excerpt from my Medalist history article:
"1966
The Enterprise Manufacturing Company officially changed its name to Pflueger. Shakespeare Tackle Company acquired Pflueger and manufactured the reels in Akron, Ohio, from 1966-69. The letters DA were added after the model numbers."
