When photographed in Sepia, this typewriter looks like it could have been made in 1879 instead of 1979. (Just imagine it with the strange stenciled flowers found on any 19th Century typewriter, The flowers were put on them to make them "less ugly," and to help them appeal to women.)
It even has the same edge treatment as many 19th Century typewriters. Also, notice the angle of the front of the machine; this is incredibly similar to that of Christopher Latham Sholes' typewriter of 1873. (The main differences in the styling are: the flatness of this machine, and the visibility of the printing, the lack of painted flowers, and the ease of operation--the first typewriters were very confusing.)
Just to clarify, this typewriter was manufactured in 1979. However, I think it would look very natural in the Old West, or placed on a table in a ghost town (if the logos were changed). Here are some logo ideas:
