Poles for signal wire?

[rob love]

So I spent Saturday, along with Derk Derin, out at our favorite surplus yard where we bought many things we never even knew we needed. I made the climb to the ceiling of the store and retrieved these poles, which I suspected were cleaning rods. Turns out the two with brushes are, and they will join my 2" mortar downstairs. They are nicely marked with CCM so are Cdn made, which is great. The brushes unscrew easy enough, but I am going to have to use some tools to try and un-thread the two halves of the handles, as they seem to be stuck.



The other poles are what I do not recognize. I did find a marking on one where it was made in Ottawa in 1940. But what are they? They join together for quite a length, so I am thinking perhaps for stringing signal wire up into the trees?
