Here we have a vintage, Perko, Perkins ML Co. Brass marine lantern. Green glass. Corner/wedge type fitting. measures approx 4 3/4" tall, 4 1/2" wide (at widest points) and 3 3/4" deep (front to back), untested, assuming it could/will probably need new electrical hardware. Brass has wear, surface staining and a couple of dings on top. Glass is good. Thanks!
