This is a glass-jar style lawn and garden sprayer made in Freeport, New York by Carac. This “Even Rain” sprayer has a metal topper where users would connect a hose, which screws on to the jar holding whatever you might want to spray.
This was manufactured in the 1950’s right in New York on Long Island. The condition is outstanding, with just a little bit of mineral buildup on the underside of the sprayer, a little on the outside, and a light amount in the jar. No cracks or chips, rubber is all still in great shape, and the labeling is still amazing!
