are a set of 10 Vintage Slingerland Radio King nickel bass drum lugs complete with the original mounting hardware,springs,inserts,felts, and 1-slingerland logo washer per lug. the mounting hole spacing on these are 3" on center. These are in perfect working order, and i would say good average shape for their age. I have more parts from this bass drum on auction and gladly combine items into one package to save on shipping. These parts were pulled from an old Vintage Slingerland 14x26 Radio King bass drum with the brass Chicago,ill. U.S.A. badge.
