This is a pretty nice original brass Lunkenheimer Crown Swingtop drip oiler in the “4″ size. It is about 2 3/4 inch in diameter and about 6 3/4 inches tall overall. It has 1/2 npt pipe threads that are in great shape. It has some very minor wear overall but has nice patina. It was originally nickel plated but most of that is gone. Both of glasses look to be in good shape and after some cleaning and gaskets it should be ready to be used on your project. These larger Crown oilers are pretty tough to find. It would be a nice way to top off any engine or machine that needs a nice oiler. It would even make a great spare on the shelf. The pictures tell the story. You’ll like it.
