Vintage Neptune Meter Trident New York Water Meter Plaque

Up for sale is a marvelous vintage Neptune Meter Co. Trident Water Meter Cover / Cap. It has a serial number of 11133937. I am not sure if it's made out of solid brass or bronze. Measures approx 4.25" in diameter by 2" tall. It is mounted on a wooden plaque with felt lined on the bottom. This item was always kept inside of a box and never on display. It looks brand new and only showed very limited patina inside the cover. Great addition to your collection. Thanks!
