Here’s a beautiful set of brass Perko oil burning navigation lamps.  Set includes red, green, and clear.  Each lamp measures 12 inches tall, not including the hanging loop.  The port and starboard lamps measure about 7 1/2 inches wide and weigh about 3 1/2 pounds.  The clear mast light measures 6 1/4 inches wide and weighs almost 4 pounds.  All are marked “Perko” on the back.
