This is an extremely hard to find original crankcase breather for a 1 hp International Harvester Mogul gas engine. It is part number 3880T and is in good used condition with no cracks, breaks, or repairs of any kind. It mounts with two holes 2 7/8 inches apart on center. It has nice original patina and is ready to be used on an engine. If you need one for any reason here’s your chance. The pictures tell the story. It will likely be a long time before another one comes along. I can be reached at 262 573 193 1 if you’d like to talk about it.
