GMC T D(G?)(H) 3501(or 2). T for Transit; D (Diesel - Toroflow if I recall) or G (Gas); H is Hydraulic Transmission (automatic).  M would be for a manual transmission, but Bill Luke's Old Look Buses book doesn't show any M's.  GMC's nomenclature was then the number of passengers, model in the series -- so 35 passengers, first model in the series (or second model in the series).  

Probability, from production numbers is TDH-3501, 1049 were built, as opposed to a total of 316 for the Gas, and 3502 models.    

The dual headlights tell the story (along with size, and window count).  This was the last model of the old-look bus built, and they continued in production after the Fishbowl (1964-1968).  

One of the companies I worked for used them on light density city lines in the Boston suburbs.  I was a supervisor there, I don't recall whether I ever drove them.

Brings back memories... Many transit authorities ran these "GM Oldlooks" through the '50's and '60's and some stayed in service well into the '80's.  We have one in our Transit Museum collection.  If you pull up to a stop light too close, you have to duck down and look up to see the light change because of the overhang above the windshield.  There's also a low ceiling above the driver that I've banged my head on 10,000 times.

Beautiful, and just the right size for a traveler.

A bunch of them used Buick Straight 8 engines.
