MkV Heliograph wanted

[BCA]

A shame; I recently sent my extra heliographs to a militaria auction. The common configuration has just a single mirror but the duplex mirror system shown in one of your photos is the nicest set-up. There is also an electric lamp, battery powered; the one I have is labelled: Lamp Electric Signalling Daylight Mark II-1918. I've seen tripods made in Toronto with WW2 dates. Others I've seen have WW1 dates. Somewhere I have a books of communications devices that includes a full description of the heliographs - can't put my finger on it right now but will keep looking.
The photos show a particularly nice example - in particular the nice condition of the duplex mirror case and contents. ............. Brian

Thanks Brian for the reply and information!

Darn, wish I had found this tripod sooner. In all honesty I had never heard of a heliograph until I picked this up yesterday. I love this hobby as there is always something new and interesting to learn about!

My tripod has Mis-Can-Ada Ltd. Ottawa 1941 pressed into the wood on all three legs. Tried to do a Google search for the manufacturer, but all it kept coming up with was Miss Canada, which was most certainly a pleasant distraction.

If you find anything new, please let me know. Would also be interested to know what your battery-powered signal light looks like.

Thanks again,
David

It could be Mississauga Canada. I have this same name on a trench mirror dated 1943.
