Yeap, ive seen the american version of the withes ball, im in the south of england, those large silvery ones are unfortunatly an oversized christmas decoration or friendship ball. These old one's in handblown victorian glass where never used as a fishing float as far as I know but I could be wrong, a glass fishing float dosnt sound very practical to me, what happens if you smack your float with the bow of your boat?
Also it lacks a means to hang it up, as its all one sphere of glass with a blob of glass over the bit where its been blown, it would have had a net bag at some time in its life.
