Made for the Dept of Ordinance in 1940. Looks just like a medium sized waist, or tail Machine gun. Presumably used to monitor and record gunnery skills. Has Several doors to access light bulbs and for film loading. This is a stunning article-if not a little ominous.
Paint is very good.
Plunger thumb trigger between handles is spring loaded, turns on light and engages film magazine, there is no film mag. BIG history here. Ships at actual. If you want this shipped out of the country, get someone else to do it, I'll send it to them. Please pardon possible innaccuracies above.
