Hi:

     I recently acquired a Fox Stunt that I need some help identifying.  It was given to this guy in 1968 as an anniversary model.  Perhaps the 20 anniversary model.

      It looks like the typical Fox stunt with a few exceptions.  One is the case has a somewhat textured outside finish.  The other thing is that the crank disk is much  thick and has a deep concave bevel pointing into the hole in the shaft. The hole in the shaft looks much larger than the standard Stunt.  The bore in the venturi also looks a bit larger. 

     This was a great running engine 30 years ago!

     Any idea as to what it is?

                                                                                                    Tia,

     Hi:

     I did some research and I think that this engine is a 1963 Anniversary engine.
