I was out rummaging in the back of an antiques store the other day and came across an old zebco 33 for two bucks that I couldn't pass up. I'm not sure how old it is, but there're no stickers, or labels, and the only text on it is "Zebco 33" on the metal front piece and "made in usa" under the seat. It came on a heddon pole that was made in the early 60's, but I'm not sure if the reel is that old or not. Anyway, I cleaned it up and started to look at it, and i can't seem to get the drag to work. none of the levers or knobs are labeled, but there's a furled knob on the left side down near the reel seat that has "on---> off<---" on it. Does anybody know if this is the drag? i crank all the way to one side and the other and I can't seem to get the reel to strip line off. Also, if anyone knows how i can find out how old this thing is, let me know.
