This is an original cast iron cylinder sleeve for a 1 1/2hp International Harvester Type M gas engine. It is part number 9535-T and has a 3 1/4 bore. I believe this is for the ignitor fired engines but please do you homework to be sure it will work for your application. It is in excellent used condition with no cracks, breaks, or repairs of any kind and the bore is in great shape with very little noticeable wear. After a light hone it should be ready to be used on your engine or put on your shelf for a spare. If you need one for an authentic restoration look no further! The pictures tell the story. You’ll like it. I can be reached at 262 573 193 1 if you’d like to talk about it.
