This is a very hard to find original brass oil sight gauge for a hit and miss gas engine or tractor. This style was used originally 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 1/8 npt threads are in great shape. After some minor 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.
