From The Ministry Of Technology UK Mobile Cinema 1967
I was researching British theater systems when I stumbled upon these really cool mobile theater systems. Unfortunately the Ministry Of Technology did not use it to take the latest Hitchcock film on the road but rather to educate the industrial base of the latest industrial production techniques. However one of these has been restored and is being used to show movies that are more interesting. The restoration process and in depth history is at the Vintage Mobile Cinema site at http://www.vintagemobilecinema.co.uk/
The seating capacity is 22.
