The only way to operate the torch was to hold the Morse code switch down.
The end cap has the following stamped "CCB" "Made in Canada" "AP16001" and a "C arrow".
I was told these were used for beach landing operations (D-Day?), the closest I could find to matching this was a description "Admiralty signal torch"
Apparently different beach landing zones had different light codes, this one has a blue glass filter.
Unfortunately the bulb and spring to hold the batteries are lost.
