Time for another Five-Dollar Mystery! This is an Agfa camera, and beyond that I've got no idea. Yet. On the outside, it's pretty simple. There's a dial-up flash reflector dealie, you can switch between "outdoor" and "flash" modes, and that's pretty much it.
The insides are the interesting part. It uses a "Rapid" film loading/winding system. It seems like the thing requires you to have two canisters in there, and the camera has no rewind dial anywhere, which suggests the take-up is done into a second canister and that one is pulled out without rewinding. That would explain the "Rapid" moniker. On the back, they recommend Agfa AG-1B Blue or AG 1, when shooting with a flash. And there's an empty battery compartment that I'll need to figure out. This should be interesting!
