Bow Compass with Pencil Point Sold by Keuffel & Esser

Bow Compass with Pencil Point Sold by Keuffel & Esser

Usage conditions apply
This tarnished German silver bow pencil has a ring connecting the instrument to its ridged cylindrical handle. It is marked: KEUFFEL & ESSER CO. (/) GERMANY. The disc adjusting the instrument's width is between the legs. Thumbscrews on the back of one leg and the front of the other permit adjustments to the height of the pencil and pricker points. The instrument has no pencil lead.
The instrument does not appear in K&E's 1892 or 1909 catalogs. K&E sold a similar bow compass from at least 1921 to at least 1936, but that instrument was made in the United States and had bolts in each leg at the ends of the bow screw. Therefore, this object may have been imported before 1892.
