I saw this photo and a 6-1/2 minute video on the website for Machinery Consultants, Inc. in Salt Lake City. This is supposedly a 17" x 36" Model 612.

I know that some members here have some strong opinions about this dealer and I haven't bought anything from them, alhough I did visit them several years ago.
They do seem to paint most of their machines which can be a mixed blessing.
However, the videos that they make show details about many of their machines that I would otherwise never know.
