I was unable to locate the production number of the above rig on any of my very incomplete Mack delivery lists. As for your latest comments/questions....
1- Tanker capacities have varied greatly over the years. In 1948, a Tanker could have held as little as 500 gallons, compared to the typical 2000 to 3000 gallons on today's tankers. Mack, along with most builders, did not specify pumpers or tankers by their production numbers. The rig, whether it was a pumper or tanker, was all Mack-built, or it would have had a different type of designation for the production number. Mack built complete fire apparatus for many years and also sold fire apparatus chassis to other builders, but there were differences in the production numbers that show which was which.
2- I am not familiar with any Mack motor called a "CT", nor am I familiar with the "Lanova" engine. The motor used in the type 75 of the E-Series was a model ENF-510A.
