This is the first time I've used a Lettera 22, and I can see what the hype is all about. It is a true pleasure to type with this machine. This one is even better than I expected, since it has a Spanish keyboard with n-tildes, accents, and umlauts. The cent/@ key is used for semicolon/colon, so I won't be writing any email addresses with this Lettera.
The serial number is 158503.
If anyone has a catalog of Olivetti typewriters they could share, I am curious about their name for this chrome/silver finish.
Thank you!
