This is a very rare Piccola, which is an early Corona 3 that was branded for sale by a Berlin company that primarily sold typewriters in Germany and Austria. Mechanically it’s identical to the earliest Corona 3 typewriters. This is one of about a dozen that are known to still exist.
This one is serial number 21841, which means it was very early because Corona 3 production began at 20000. It has all of the earliest features; note its lack of a pigeon Iogo, the straight ribbon selector, and the pivot bar segment.
