Quote:This is a rare Mack B21, one of only 9 produced. It was one of six delivered to Seattle in 1958. The longer hood was required to cover the massive 324 horsepower Hall-Scott motor. The six Seattle B21's had Heiser bodywork and pumped 1500 GPM.
Dave;
Of the other three B-21's built by Mack we have only seen pictures of units assigned in Memphis, and Ogden. Can you or maybe Mike provide some history of where the other three units where assigned.
