The first Royal portables were afaik the boxy design, the 'Model P' and so forth. Replaced mid 30-ies by the rounded squarish design.
When did Royal make a small portable typewriter in a streamline design?
There is one listed on the local Ebay version for sale with a cover that looks more like a Corona streamlined design than anything else but marked Royal.
Where does this fit in the Royal line of portables, wondering...
