I'm thinking this is a brass nozzle, I could tell easily if I had it in my hand but all I have is this picture. It is for sale on local Facebook site. Can anyone tell me if it is brass or not from the picture? Also would like to know approximate year of manufacture? I see Riess, Parker and NB on it. Thank you Kirk T.
