Set of Drawing Instruments

<< >>
This mahogany veneered case is fastened with metal hooks and lined with black velvet. The top has a green sticker marked: 14. An L-square, ruler, case for pencil leads, and compass attachments appear to be missing from inside the case. The instruments that remain in the set include:
1) 6-1/8" steel, German silver, and ivory drawing pen. The handle is broken.
2) 4-1/4" German silver and steel dividers with removable pen and needle points.
3) 7/8" German silver joint tightener.
4) 5" German silver and steel fixed-leg dividers.
5) 5-3/4" German silver and steel dividers with removable pen point, pencil point, and lengthening bar.
According to the donor, the U.S. Coast & Geodetic Survey acquired the instruments on September 24, 1912, and last issued them to an employee on January 19, 1927. No sets like this one were found in Keuffel & Esser, Dietzgen, or Gurley catalogs.
