Here is a shirt from back in 2005 in Rochester, MN just 30 miles south of me. The crazy looking red and yellow machine is a Massey-Harris "Mare". If I remember right the man said this was a machine used in WW2 for loading bombs. Later used in a lumber yard for moving large piles of wood. The man who owned it at the time of the show converted it to a Massey "Mare". He would drive it through the parade and stop and mare would have a baby Pony come out. Several years after this show the man died and had an auction, it now sits in my brothers shed about 30 miles from me. He thinks I should have it but it takes up alot of room I don't have.
