The statement at the bottom of the photo: "Scene at the Rudge Whitworth Works at mid-day" shows workers at the huge manufacturing plant, possibly at the end of the work day. What a lot of employees! Most of them young, grade-school age children, with a few adult chaperones.

This company was in the UK. And, Rudge Whitworth was a manufacturer who operated from 1894 - 1946. Here's what Wikipedia says about it:

Rudge Whitworth Cycles was a British bicycle, bicycle saddle, motorcycle and sports car wheel manufacturer that resulted from the merger of two bicycle manufacturers in 1894, Whitworth Cycle Co. of Birmingham, founded by Charles Henry Pugh and his two sons Charles Vernon and John, and Rudge Cycle Co. of Coventry.
