Interesting where this is going. I had a hunch it might be an item with a similar history to the Satchel Signals Bag, but I was not certain. Probably a bit early in the investigation but we seem to have at least two near identical designed bags with two different stock reference numbers but both serving the same purpose of storing Aerial F Rods. And we now know another version with carry strap exists for the same purpose. You would think that a bag designed for a specific purpose would retain a common inventory number over it's service lifetime, regardless of the Wireless Set it was matched up with, but NOOOO, the designers have to torment us years later.
Neither the Mk III Canadian 19-Set Manual, or the Truck and Ground Installation Manual for the 19-Set reference this bag. The latter seems quite odd. True that at least with the 2Kx Series of 15-Cwt Wireless Trucks, the F-Rod Aerial Sections had their own steel storage tube mounted on the upper left front corner of the Wireless Box so they were within easy reach for the crew when on the roof of the box. But what did they do with the F-Rods if they were humping the 19-Set to a remote work site? We must still be missing something on that point.
Looks like a list of sets using this bag will be in order and with luck we will be able to match up specific stock numbers to specific sets and fill in some more wireless blanks in the process.
Didn't expect an easy answer, Bruce, I was expecting a good tree shaking.
