Does anyone know what's the name of the font? I know this is an 'American Typewritter' variation but can't find which one?

Perhaps it's this?

The font is premium, but I'm sure you can obtain it somehow.

That wouldn't be a problem as I'd buy it but it's not that unfortunately.

have you tried http://www.myfonts.com/WhatTheFont/ ?
