You are looking at a Vintage Brass Storz 65 Fire Hose Nozzle. This nozzle was removed from a tug boat that was being torn apart for scraps.
This fire hose nozzle is made out of brass and rubber. You will see that it has a handle and the words STORZ 65 and PN 50 as well on it.
You would have to use your creative imagination to figure out what you would do with this, but it would make a great addition to your nautical collection!
