Pantograph, Dietzgen Model 1875

Description
This instrument has four hardwood bars with mahogany edges. The bars are 41 inches long. The fulcrum, joints with thumbscrews, and interchangeable tracer and pencil points are metal (no lead in the pencil point). Each bar has thirty-four holes drilled in it. These are spaced the same way on each bar, but not at equal intervals. The holes are labeled from 1 to 34 and also from 1 1/8 to 8. The device may be used to enlarge a drawing up to eight times the original size or reduce to as little as one eighth.
A mark on one bar reads: EUGENE DIETZGEN CO. (/) CHICAGO-NEW YORK (/) SAN FRANCISCO-TORONTO-NEW ORLEANS.
