This was typed on a Smith Corona Electric that I found in my back alley a few years ago. I've actually recovered two machines from the same alley, different locations, different years. I keep my eyes open each time I walk there, but it has been a few years since I found the last one.
I think I'll have to invest in some white out. I see that I missed a few letters here and there when typing out some tweets! My @ symbol looks like a blob, too!
