Sperry-Sun Drilling Services, Inc. provided drilling services and equipment to the petroleum industry, first in Texas and the Gulf Coast and then world wide. This collection of historical miscellany was collected for a 65th anniversary celebration in 1995 and other materials from the company's public relations office. The principal series is the Historical file. It contains material assembled for the 1995 company history booklet. Many of the documents dealing with the Sun Oil Company, members of the Pew family, Elmer Sperry and the Sperry Gyroscope Company are photocopies purchased from other Hagley accessions.

Sun Company is a petroleum processor and distributor incorporated by Joseph Newton Pew, Sr. (1848–1912), with his eldest son Arthur E. Pew (1875-1917), under the laws of New Jersey in 1901. In 1902, the company built a refinery in southeastern Pennsylvania on the Delaware River at Marcus Hook to process crude oil sent from Texas by ship. This collection contains plant and production records for the Marcus Hook, Pennsylvania, refinery of the Sun Oil Company. These records provide insight into the plants' finances, primarily through material and labor costs dating from 1903 to 1929.
