I was impressed that the plastic on this Seville, no cracks and not brittle. Then I put the outer lid back on (it cracked and a chip broke off). But then the outer case lid the most exposed part of the typewriter. The typewriter itself for over 40 looks & feels great and it’s orange color looks like it would glow at night. (It looks like a Citizen XL (Columbia) and was made by same manufacturer.
My Underwood has its Western Union serial number WU5739R and I checked the number under the foot is 205320. I guessed 1909 based on design, but the serial number places it at 1908. For me 1908 is a great year for an Underwood.
