Rob,

That would almost certainly be a post-war mod.

Here in Australia post-war all the left hand drive American vehicles required a similar signal because the driver was on the wrong side and his hand signals could not be seen by following drivers. As this truck is right hand drive in Canada it would be fitted for the same reason.

Looks like a rod went across the back of the cab to a handle for the driver to operate.
