SOLD - This is a nice vintage Lyman 438 Field Rifle Scope. Scope measures 15 3/8/4" in length and has adjustable target mounts that, according to my Internet research, work with Lyman-Unertl bases. Lenses are good and clear. Has a crosshair reticle. Patent Numbers date to the 1930's. Scope has about 90% original finish and has developed a patina, with a few small areas of rust on the adjusting screws. Includes the leather lens cover which came with it. The leather shows age but there are no repairs.
