Antique Fisherman's Minnow Trap

Rare fishing bygone. Large Antique fisherman's Bottle Trap for catching minnows and live bait. Good condition. Bread was placed inside the bottle and it sat on the river bed on its side. The fish swam in to feed via the hole in the base. When it was pulled up they get trapped in the outer ring.  They could then be tipped out via the spout.
