My latest 'delivery' was an old tube-driven oscilloscope that a friend gave me. It's a Bell & Howell Schools / De Vry model, made by Heath and assembled by a student. Still has the pencil notes (V1, V2, etc.) beside the tube sockets. I'm still waiting for one more tube to arrive. You'll note the fold-back on the left side of the trace.
