Here is a vintage Ships / Boat Perko Style Lantern. No name on lantern but my best guess is it was made by PERKO. It measures 12 inches to the top of the ring.  The glass lens is nice with  no cracks or chips. This lantern also has the bottom door with working latch. Lantern Only with No inside Burner. The lantern top is brass. Please look at the pictures and see if this lantern is what your looking for. Thanks for looking at my auctions, Jim
