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 5/8 inches in diameter and about 3 5/8 inches tall. The lever moves as should. The wrench flats aren’t real crisp but the unit should still be serviceable. The 3/8 npt threads are in good shape and 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.
