Sometimes you just get lucky.
I was looking at FWD as a possible solution and another view of what looked like your Big Rig just popped up and was close enough to investigate.
It would seem this is a Winther or Winther-Marwin snow blower built in Wisconsin sometime between 1920 and 1927 from what I could find.
Rather a rare bird I would suspect, I had never heard of the marque before.
