U.S. Service Issue Pocket Signal Disk
The AC purchased a U.S. Service Issue Pocket Signal Disk at a Georgia antique mall for $4. The two-sided pocket size primer has the International Morse Code one one side, and the Semaphore International Flag Code System on the reverse. The original price for the primer was .30 cents. This item was donated to the NCM. Pictures of the Signal Disk are included here.
