Hi there ~ I was looking for the same instruction manual, and I found this website: http://users.lewiston.com/ejorgens/office/smithcorona/smithcorona.html It appears to sell manuals for a lot of different/vintage typewriters, including the smith corona portable sterling. (I'm assuming you are refering to the 1938 - 1949 model) Look for the Clipper/Stering manual if this is the age of your machine.
