Years ago, all the baitshops in my area of Florida, had a line of cane pole friendly items.
Among them was 2 natural cork items. The first, was a hook keeper. It was a round disk, of cork, with a covering of chromed tin, with a hole in the center. You attached it to your pole, with the small diameter spring, attached to it. You stuck your hook, through the hole, into the cork.
I think I still have the remnants of one, somewhere...
The second was a torpedo shaped cork float. I think Betts made them (not sure). They had a brown, cotton thread loop through them. Two tags on one end, going through the cork, forming a loop, and back through (the two tags). The thread was secured with a thin white, paper band, with the name on it
To use, you inserted your line, through the loop, and pulled the tag ends. It became a slip float. It held the line good enough, when they were new, to adjust up and down, with no bobber stop.
The corks came in about three lenghts, 3/4, 1.5, and 2 inch. They were smaller around the center, than a dime.
Does anyone have a line on the floats, in natural cork? I'm pretty sure, the hook holder, is a gonner....
