The first case is for the heliograph which in this case had mirrors with a 5" diameter. In theory it would be capable of transmitting signals up to 50 miles in the daytime and 10-25 miles at night with the proper moon. Saw main military service from roughly 1850-1920 but were also still in use through the end of WWII in some of the desert regions of North Africa and in India.
The U.S. Calvary used them in the American West and the Mounties may also have used them for regions in Canada where telegraph services didn't always exist before the turn of the century. Not sure on the second case.

The last pics have a family resemblance to the "Bags, Aerial Gear", part of the accessories for a complete WS No 19 set station.
The bag contained the ropes, hammers, sledges, pegs, insulator base etc required for the 20' or 34' aerial vertical mast.

Thank you for the responses.
I was in the Mounties 30 years and saw a lot of artifacts. I will have to dig deeper to see if in fact the Mounties used the Heliograph at all. Back in 1978, the Heliograph would have had 10 times the distance coverage than that of our police radios. The second case is still a mystery, but I like the radio relationship. Now all I have to do is fill them with the proper gear. Guy
