Queen Mary visits factory.
Queen visits a factory. Location of events unknown.
Royalty; industry; manufacturing. Queen Mary stands talking to a man with another man in FG; bent over a work table. She then walks around & looks at things; with a few men. Comes round corner walking with her cane. Very wild place -- looks like a house converted into some sort of light industrial factory. Pendulum things hanging from ceiling moving like mad inventions. Walk into room with men sitting at long table doing work on paper -- drafting?.
