World War II code key made by Lionel. I cleaned off the dust but did not polish anything. Belonged to my ex-husband left to my daughter upon his death. He was a Vietnam Vet and radio operator in the Marines and radio amateur from high school age. He kept his collection in extremely good condition. Please check out photos and let me know if you would like any other information or photos. No box or other accessories. I am shipping in a medium flat rate box to be sure it is protected well during shipment.
