Hi Laurenz
I don't know if Olympia ever made them, but I'd venture to say a really rare keyboard or key map would be a true Dvorak layout. From what I understand, the US Dvorak has the number keys in numerical order from left to right, but the true Dvorak has zero in the middle with odd numbers going up from center on one side and even numbers on the other. I have only ever seen one 1940's Royal Quiet Deluxe come up on eBay with the Dvorak key map, and that one went for close to $2,000.00. Keep your eyes open and you never know what you might find. All the best,
Sky
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.
