Musings from the desert written on vintage machines
Remington Rand? I'm basing my answer on the long stretch of writing on the rear of the machine.
Hmm, it does look like an RR ... but more like a manual than an electric. Do you ever see him return the carriage by hand? If so, then the wiring is just for show.
I'm thinking Teeritz and Richard are correct. I thought it looked like a manual but the automatic movement threw me off. In the skit the carriage moves without Joel touching it, so I assumed they used an electric. But now I'm thinking they modified a manual RR with some fancy-schmancy animitronics.
