This is an original cast iron piston and rod for a Stover CT-3 and possibly a model K hit and miss gas engine. I believe it is NOS, new old stock, and seems to never have been used. The rod is part number 201-CT-3. The piston is part number 7CT3. The assembly is in excellent condition with no cracks, breaks, or repairs of any kind. The wrist pin has no noticeable wear. The connecting rod bearing looks to be in new condition. The piston is 4 1/4 inches in diameter. Please measure your engine to be sure it works for your application. These original Stover parts are exceedingly tough to find in the wild or even at swap meets! If you’ve been looking for one to complete a restoration or to replace your broken or repaired one here’s your chance. The pictures tell the story.
