Royal KMM typewriter from around 1939

Royal KMM typewriter from around 1939 I don’t know typewriters, but I’m basing my information on research and the picture and information on the screen grab that I included in the pictures. But the information does make sense. The typewriter has the Royal name, but it also has a newer sticker from the AAA typewriter company. So AAA worked on it and replaced the keys. I found one with the same keys that were installed in the 1950’s. It does come with a falling apart cover. It’s measurements: About 16 inches wide About 17 inches deep About 9 1/2 inches tall It needs a servicing. Some of the keys stick. One button is missing shown in picture. There’s ware to the finish and some rust on the chrome looking leaver in the top left of the machine. I’m asking $60 cash for the typewriter.
