This is a very to find large original brass priming cup for a hit and miss gas engine or tractor. It is in as found condition from an old shop and measures about 1 1/4 inches in diameter and about 5 1/2 inches tall. The lever moves as should but it chould used a new compression spring and pin on the backside. The 3/8 npt threads are in good shape and with just a little effort this priming cup should be ready for use. It would also make a great spare on the shelf for a future project. The pictures tell the story. I can be reached at: 262 573 193 1 if you’d like to talk about it.
