There were some S&W NY-1 guns that never were sold to NYPD vendors or such, but were over-runs and went to the commercial market. I bought a 4 inch Model 64 NY-1 brand new in the box from Harrison Carol in 1988. Round butt, DAO, spurless hammer, frosted or bead blast finish, S/N AWT29xx. Mr. Carol advised me there were about 60 over-run guns in that batch. It's still unfired and I ought to find it a new home.
