The Lubitel 166B is a wonderfully crappy Russian rip-off of the Rolliflex Twin Lens Reflex (TLR) camera. It basically does everything the Rolliflex does badly, is badly made, has bad optics, light leaks, and is prone to breaking. It uses 120 roll film and it's wonderful.
Mine hasn't been used for over two decades, but I still enjoy looking at it.
