Here’s what I found
The ribbon arrived, so I built a little jig for spinning a ribbon spool in an electric drill and loaded a spool. Evidently wasn’t thinking too well as I put the carbon on the inside. Wound a second spool with the carbon on the outside and loaded it into a typewriter.
Turns out the ribbon is single use so the letters overlap on a normal typewriter. A 1968 Royal Sabre winds the ribbon through faster than the norm, so this single strike ribbon works just fine and gives really crisp lettering on the paper. I received 24 rolls of 450 feet of ribbon per roll, so I have lots to work with. All the best,

We humans go through many computers in our lives, but in their lives, typewriters go through many of us.
In that way, they’re like violins, like ancestral swords. So I use mine with honor and treat them with respect.
I try to leave them in better condition than I met them. I am not their first user, nor will I be their last.
