Vintage ELKHART MFG Firetruck Nozzle Apparatus GPM 95 Foam In-Line Eductor Hoses 1940's. This nozzle came from a friend of mine that was a fire truck captain in Reno, Nevada many years ago.
What's missing is the on-off eduction valve & hose. It worked left to right, an 1-1/2" hose line connected to the brass swivel, and an 1-1/2" hose line & fog nozzle attached to the right side make threads.
The downward piece had a threaded cap to attach an on-off valve, which in turn had 5' length of clear plastic tubing attached to the valve. For foam operation, you stuck the plastic tube into a 5-gal pail of foam, turned off valve, then charged the 1-1/2" line when water was flowing, you'd now open the valve, and some of the stream would go into the 5-gal pail & "educt the combo water/foam mix into the discharge end of the hose/nozzle. The educator casing measures 11.75" long by 3" wide at the mouth.
It's a cool display piece. This item is in the category "Collectibles\Historical Memorabilia\Firefighting & Rescue\Hoses & Nozzles". The seller is "wares-the-stuff" and is located in this country: US. This item can be shipped to United States.
