This lever has been sitting in a closet in my parents' home. House was built in 1959 then expanded in 1978. Both sections have windows that use they type of lever, so it has either been sitting there for about 60 or 40 years. Some scratches/scuffs from other items that were stored on the same shelf over the years, but it has never been used or installed. See photos for measurements which are end-to-end on each piece.
