An octagonal brass tube with a round handle has a slide that extends its length to 8-5/8". The handle unscrews and can be removed to function as 4-3/8" brass and steel dividers. The other end has an unnumbered one-inch scale divided to twelfths.
The other two tubes are made of steel and have rings or sleeves that slide up and down to move the crayon and allow the user to grasp the crayon. The 6-1/4" crayon holder is not marked. The 5-1/16" crayon holder has a four-inch scale divided to 1/4" and numbered by ones from 1 to 4. Its top is engraved with a drawing of a bearded man.
The dates of objects purchased with these writing instruments suggest they were made in the 18th century. Holders for wax crayons, chalk, or charcoal sticks were known in Europe by the 17th century and widespread by the 18th century. They were employed by artists and draftsmen.
