Vintage 1940's Firetruck Nozzle Apparatus GPM 95 ELKHART MFG Foam In-Line Eductor. 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. The nozzle is used with age wear on the brass because of obvious consistent hard fire service duty. Very solid and in great shape. This item is in the category "Collectibles\Historical Memorabilia\Firefighting & Rescue\Hoses & Nozzles".
