BUILT BY JOSEPH GWEN DAN BUNCHS FATHER IN LAW
I BOUGHT FROM A COLLECTOR WHO SAID HE WAS SURE THIS ENGINE IS A BUNCH PROTOTYPE SINCE IT HAS
NO MARKINGS AND IS STILL IN THE ORIGINAL WOODEN BOX. IT APPEARS TO HAVE A PISTON RING AND THERE IS NO WARE IN THE COMBUSTION CHAMBER
LISTING IS NEW BECAUSE IT LOOKS TO HAVE NEVER BEEN FIRED
COMES WITH EVERYTHING IN THE PHOTOS
