Western/Cowboy Black Spurs w/Etched SIlver Trim and Rowels, Unmarked For Sale

Western/Cowboy Black Spurs w/Etched SIlver Trim and Rowels, Unmarked. Not sure of metal but magnet sticks to it. Silver may or not be real; there is some green corrosion dust noted on several areas of the spurs mainly near the rowel section. Some rubbing inside the spur from boots. One rowell has lost its black color. I had a pair of blued spurs but not sure if these are called blued or not. Please see photos. Selling as is.
