We can see the combination of features distinguishing this model with a GN engine from the earlier TEB model and the later Model 15-45 buses: higher body sides making the first and second door look rectangular rather than square, 10-bolt front wheel hubs, and the flat cowl below the windshield.
The major changes to the Model 15-45s are the completely redesigned engine and transmission on a heavier frame. The 45 hp engine features a removable head and a pressurized oil system with an oil pressure gauge added to the dash. The longer, four-cylinder engine increases the wheel base by 4.5 inches resulting in a longer hood and front fenders. The new transmission has a more traditional shift pattern and is easier to shift.
Notice the metal-covered trunk at the back for passengers’ luggage rather than the simple canvas cover found on the previous Model TEB buses, a carryover from the stagecoaches.
