This is a very to find large original brass oil sight gauge for a hit and miss gas engine or tractor. This style was used original on some Rumely tractors, Cushman engines, and Ford Model T’s. It is in as found condition from an old shop and has no cracks, breaks, or repairs that I can see or know of. The drain valve moves as it should. The 1/8 npt threads are in great shape. The glass tube is a bit dirty on the inside but can easily be cleaned. After just a little cleaning this gauge 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.
