I'd suggest that you post a photo of your machine for reference (read the FAQ if you're not sure how to do that). Also, there's something not right with the serial number you posted: there are too many digits, and the 10 typically has a letter (or two letter) prefix before the serial number. Finally, the reason that you can't find photos of a maroon-coloured 10 is that your typewriter has more than likely been repainted at some point during its century-old history.
