Burke Jig-a-Do Eels were popular in the 70's. They were Burke's ( who was and still manufactures lots of rubber lures) answer to Garcia's marketing of Al Reinfelders Alou-eel which was a result of Rienfelders partnership with his fishing pal Lou Palma in Brooklyn NY.
The current ALL Tackle World Record Bluefish was supposedly taken on a Burke Jig-a-D0 eel by one James Hussey of North Carolina back in 73 I believe.
Hang it up, they haven't made 'em for decades and they aren't worth anything collecting but it is a piece of angling history.
