Back for more advice…

I found this Olivetti Linea 98 at a thrift store today. I paid the guy a few bucks (refundable) to hold on to it for me.

Newbie here (see my previous post) so can someone help me out?

1) depending on the condition, how extensive would repairs be?

2) is it a good machine, all things being considered? (He was clueless so obviously not as great deal of help.)

3) if I buy it and get it working, are replacement ribbons readily accessible?

Thanks for any insight you can provide.
