The lantern shows rust and wear. There is a dent on the top of the lantern. The globe has a couple imperfections, they appear to have been done right from factory. There is a line that runs near the B&M RR embossed logo around half of the lantern. It is not a crack as it feels like it is raised from the globe.
There is a couple other smaller lines higher up on the globe. And a perfect restoration project. Feel free to ask any questions.
