      Did any early RBM manufactures stamp the serial number in the
      brass transom screw handles?
      I’ve only found a couple of casting numbers so far, but
      today found stamped in on transom screw handle "4 7"
      and the other handle "4"
      I suppose it could be that the part being brass they stamped
      the casting number. The "7" could be worn off the one handle,
      as the "4" is very faint.
      If 447 was the serial number, it would seem too low, as I’m guessing
      that the Model M was made circa 1916, and believe Wisconsin
      was making outboards by 1913.
      Perhaps there was a separate serial number tag attached, that’s
      long gone.
      Can’t believe there’s not more info "out there" on these motors. 😕

      I’m finding bluish / gray paint here and there. Anyone know what
      the original color scheme was on the Model M?
      Thanks.

        very interesting topic here
        sorry , I can’t help you with info, but I will follow this because I have a Wisconsin also.
        like on your motor, I can’t find nothing on my motor / parts too.

          Kees, hopefully we’ll both learn something. They must have made quite
          a few of them. Believe I read something that the US government used them
          down in the Panama Canal. Can you post a photo of yours?

            I looked at the stamped numbers on the transom screw handles
            again today. I believe I now see a number 1 as well,
            so if it’s a serial number divided between the two handles,
            it’s 4147.

              It wasn’t the Government using Wisconsin motors in the Panama Canal.
              Rather, they were displayed in the Panama – Pacific Worlds Fair
              in San Fransico, in 1915. It was suppose to be to celebrate the completion
              of the Panama Canal, but was more about SF getting over the Great Earthquate
              of 1906.
