Olivetti Underwood Lettera 31 Typewriter Instructions Italy Gray With Green Carrying Case

Looks to be from the late 60's based on the serial number. 

Made in Italy

This is in good working condition and shows some normal wear from use and age but needs a good cleaning and some maintenance.  The H key and another key sticks some.  The ribbon is about out and will need to be replaced. There is a red label with a name on it as shown in the pictures but you should be able to get that cleaned off.  The green carrying case shows a lot of wear and some edge and corner tears.  Please look at all the pictures for more details.
