I too think it is an E model Mack. The model should be E?, like EQ, or ED, I doubt it is either, but it should be an E-something.
I have a 25 Mack model AC, I contacted the Mack museum with the serial number and received a copy of the original build sheet. It had a list of all the stuff on the truck, like the inflatable tires, cab, magneto model and serial number, carburetor model and serial number, engine serial number, and all sorts of other good stuff. They also sent me some reprints of the original sales catalog for the ACs, and a reprint of the service manual.
I am sure they can help with this mack too. I believe they have the original build sheets for every Mack truck ever made.
