A demonstration at a model of a mining machine

In a room with tall windows a lean man in shirtsleeves and a tie stands beside a large sheet-metal model shaped like a funnel or chute and points with a rod at a small fitting inside it; in the foreground a young man in a striped jumper leans on a bench of instruments and watches. The subject appears to be a course in mining or ventilation technology; the place is not named in the source.
