Antique Heavy Duty Solid Brass & Glass Ship's Porthole with Gear & Backplate #GAPH2

Salvaged from one of our Naval ships from the 1940s - this porthole set is complete with back brackets and a front cover.  The porthole itself is made of solid brass, along with the bolt locks with the cover being made of cast iron.  

Measurements are 16 1/2" in diameter (measured with cover on and back plate stationary) with a 12" in diameter glass view.  The glass does have some surface scratches and is shown in pictures. No breaks or chips.  With the unit together, the depth measures 4".  So you'll have a 4" projection from a wall.  The large thick eyebolts turn into each loop lock and pushed down to the sides of the base and tightened.  The back outer bracket is 1/4" thick. There is a number "3" stamped on the cast iron lid as well as a "C" encircled. 

Note: This porthole unit is very very heavy weighing in at about 55-60 pounds.    

Shipping is included in the price.
