Japanese!

It takes some weight to get these trolling lines down where they need to be as the boat moves forward. Usually big lead balls and they don't call them "cannonballs" for nothing!

Probably seemed like a good idea from a price and "hydrodynamics" point of view, but I expect it would tend to wander back and forth underwater. The rust would be a pain too, but our friendly fisherman apparently didn't want to shell out for galvanizing.

Never fired from the driving band.

Sorry about the hijack!
