Apparatus With Extending Hose Body A new idea in fire apparatus design has been incorporated in the design of fire unit delivered to San Marino, Cal. It is a 600-gallon baby quadruple Mack pumper, built in accordance with specifications prepared by Chief Copley. In this design, the hose body slides out as shown in the photograph. From this design, the company patterned another unit for delivery to Montecito. This Mack unit carries a 750-gallon pumper, two 35-foot, 3-section aluminum ladders and one 24-foot aluminum extension two-piece, plus a 12-foot aluminum roof ladder. An exact duplicate of this unit has been ordered by Palm Springs, Cal.
