I came across some interesting 35mm Kodachrome slides while cleaning out my late mother's home. I'm trying to figure out when they were taken and I'm figuring that it was in the WW-II era, late 1930s to mid 1940s. Modern Kodachrome was introduced in 1935. I'm pretty sure that the top image here is of Washington, DC Union Station. Looking at the automobiles in the bottom image, can anyone identify models that would nail down the era, i.e. are they all Pre-War? Thanks for any ideas.
Many of the slides are in a standard cardboard mount, but are also sealed between two sheets of glass, leaving an assembly that's as thick as three stacked cardboard-mount slides and a tiny bit larger all around.
