Thanks MF and speedy! It's not the self propelled base sadly. I'm not sure if I want to take it apart and use everything as parts for my other projects or to keep it as is to show the ingenuity of a different generation. This mower has an early 1970's 160cc engine with a G3 carburetor, a base and cowling from a powerplus, throttle controller from an old victa 18 and a catcher from a Green VC-SPORT or a Green VC Mustang S. To me this is a piece of art and shows what is sadly being lost to the throw away generation.
