See the pictures as they are part of the description, appears to be a hand forged 31" brass nozzle fitted with 3" machine threaded coupler. The forged seam is visible with tons of patina top to bottom even has a slight curve to it. The incised (debossed) stamped letters appear to be N P R R on the coupler.
The reinforced end piece is also very unique, I couldn't find another one quite like it. Please visit my store for more great items.
