I found this photo from the city of Modesto California at My Link page "Northern California Bus Fans", located to the right of Your computer screen at www.norcalbusfans.com

The General Motors TDH Series "Old Look" transit buses, were a very popular and versatile standard transit bus model. Introduced during the mid 1940's, the 40 foot model was manufactured from 1945 until 1959, when the "New Look" Fishbowl Windshield models were introduced.

General Motors actually manufactured smaller 30 foot GM old look style buses, until approximately 1967. The later model GM old look TDH Series buses like the one shown here, had twin sealed beam headlights.

This photo was taken in the city of Modesto California, in February of 1979.
