Good condition original WWI US military Warner Swasey Model 1913 Telescopic Musket Sight. Original black paint finish is mostly worn away, exposing the brass construction. Optics are mostly clear with a little spotting. Complete with rubber eyecup that is supple. Comes with original leather carrying case. Leather is supple with some normal wear, stitching and rivets are tight. Case is maker marked. Hard to find Warner Swasey scope that will make a great addition to a collection!
