That Pigeon Looks Just Like Michael Keaton<br /> The Late Show with Stephen Colbert

Definitely a late model Olivetti. Either a Studio 45, which was more common in the United States, or a Studio 46, both of which came in that color.

I'm leaning toward 46 because of some of the shape of the hood as well as the white variable button on the platen which I've only ever seen on the 46 while the 45s were typically black or had the button colored to match the body color.
