Things change… the Corona 3 was sold from 1906-1939 (700,000) and modified improved with time. l8 years separate my 1912 & 1930 Corona 3 and truth be told my l912 well used, beat up, repainted Corona is a much better typer than the Corona 3 Special that looks like it was used very little and put on display. Not that this means much… two machines out of 700,000. Both built in the USA one built for the English market.
