Francis E. Vaughan and Floyd Eubanks founded V & E Manufacturing, or Vemco Corporation, in Pasadena, Calif., in 1939 to make high-quality drafting instruments. Eubanks patented eight drafting machines and drawing instruments in the early 1940s. The marks on the bow pencils probably refer to his patents, "Compass" (U.S. Patent 2,297,999 issued October 6, 1942), and "Compass" (U.S. Patent 2,298,000 issued October 6, 1942), which dealt with the design of the instrument and the process by which the metal parts were punched out during manufacturing. According to the donor, this set was manufactured in 1987.
