I've been searching for pictures of trucks this morning and came across an interesting one. This is from a movie "Walk the Dark Street" filmed in 1956. The five window configuration is nicely altered with what appear to be angled openings at the top of the side glass and the rectangular rear window replaced with an arched rear glass. I'm not an AD guy but it seems like the top of the driver's window is squared a bit more than usual? What surprises me most is the extended cab. According to IMDB the movie was filmed at Universal Studios in LA so I'm guessing a local customizer built the truck. Extended cab AD's draw attention today but this one must have been a really amazing sight in '56.
