Take a look at this! A well built, early (probably right around 1900), most likely American, 4 x 5 single-lens-reflex camera with focal plane shutter. It's driving me crazy because I keep looking at it and thinking, "I know what this is..." but I can't drag the model or maker name out of the deep dark recesses of my brain! Please, if you have any idea what this is, let me know at silver@well.com, thank you!
