Found this in a collection of stereo slides when we were cleaning out my in-laws' house. This is my father-in-law, who came back from WWII and either opened or worked at a photo store in Holyoke MA for a few years, before he started working as a plant repairman for some the manufacturing companies in the Pioneer Valley. This was probably taken in the early 50s and yes, it's Kodachrome.

He had a lifelong interest in photography and we are lucky to have many pictures of my wife's family. I have the stereo camera which was probably used to take this. It's a Revere Stereo 33, and it suffers from a poorly designed film advance mechanism. I did have it repaired once, and I managed to take a couple of rolls of stereo slides of my family, before the film advance failed again.

I'm not actually sure if this is a Speed Graphic, but it's a Graphic of some kind. All we found when we emptied the house was the flash and some film holders. The camera must have been sold. View full size.
