This is a group of five industrial foundry patterns for various valve components manufactured by Powell. These items are constructed of carved wood, likely pine or mahogany, and were used as master forms in the sand casting process. The surfaces feature original shop-applied finishes, including protective shellac and color-coded foundry paint in yellow, black, and red. Several components bear legible identifying marks. The large central gate valve pattern features raised lettering reading POWELL NEW READY 3. A bulbous pattern features an attached metal plate with a right-pointing arrow above the name POWELL and the number 3 0 0. Another pattern bears raised metal letters P W. A smaller T-shaped pattern is stamped into the wood with the characters 7 2 and 2. The reverse sides of the objects feature various handwritten shop notations in black marker and pencil, including A 6 7 1 2, 1 1 / 4 Globe, and ALUM. Some patterns have been fitted with modern sawtooth metal hangers for wall display. Overall display width: 22 inches Large center pattern: 11 inches high by 9 inches wide.
