THIS LOCO WAS PART OF A SERIES OF  ENGINES THAT COULD EASILY

BE SIASSEMBLED AND RE-ASSEMBLED AGAIN.  IT WAS MEANT TO TEACH ENGINEERING AND HAND DETERITY; SKILLS WHICH ARE NECCESSARY IN PRODUCING ENGINEERS.  WELL, BECAUSE THIS TECNOLOGY CAME AT A PRICE, IT DID NOT SELL WELL, AND  SURVIVING EXAMPLES ARE SCARCE, ESPECIALLY IN THIS FINE SHAPE.
