For a while, I didn't even know what this thing was called. It resembles my junked 470 manual typewriter. I didn't find the identifying marks straight away, so Google Images takes the credit on this one.
This ad comes from The Deseret News in 1971. It's a pretty bad image of the machine.
The large slab in the front of the machine reminds me of some of the Hermes office models. But this Royal has no means of holding paper for the typist to copy documents. At any rate, I discovered the identifying marks after finding these articles.
The serial number is partially blocked by the escapement.
The full digits are: 560-13-9428254
Or, you could just look at the neat label someone printed on the side and save you a lot of time and effort. However, the typewriter does not print in 10 point. It's too big. More like 12.
I haven't figure out what's wrong with the tabulator yet. Setting tab stops messes up the escapement and the carriage freezes when you hit the stop using the space bar. Sometimes it advances to that point automatically when hitting the return button. For now, I'm not using the tab system at all. I fixed the broken ? and + keys by simply jiggling the connecting bars underneath. Lucky me.
The 560 is an obscure addition, but an interesting one. I like the keyboard a lot more than the SCM Electra.
Power to the pen.
