There's one bakelite camera you might want to consider - the lubitel 166B. The lens is a pretty decent tessar design and I've got very sharp images from mine. It's a generally nice quality camera, even if the controls aren't refined like on a Rollei. The biggest issue you'd probably ever face with one of these would be some light leaks around the back, which can be fixed with either gaffer's tape (to seal the edges) or a home-done felt seal replacement.
