Just a thought,
Is it possible they were to be used as floats clove hitched on a running line with droppers coming off of them. One guy possibly walks with the line and the other clove hitches the middle of the " floats " to it which is spooled off a drum of nylon. He also attaches a dropper of sorts baited with hooks and bread this is then walked to the other side of the loch / lake before being trawled across the surface by the leading man.
Sounds like a couple of guys who work in a factory which produces the foam balls and have come up with an
idea for poaching.
They'd have been better off using a board but that's a topic for P.M's meethinks.
