This is the Whitehouse Beacon II. I'd never even heard of the Whitehouse company, but it was President's Day, so I had to get it. Manufacturing spanned 1947 to 1955 -- that's Truman and a little Eisenhower.
It's got a fixed aperture of f/11, and the shutter is something like 1/50 of a second. This is the early model, which includes a manual shutter option that was absent on the later versions. (I blame Ike.) I took it to Drink & Draw to shoot a roll of Rollei Crossbird slide film on it. At ISO 200, the shutter times were around two seconds. We'll see what happens!
