A precision laser engraved wood version of this famous cipher which was used for the encryption of messages of the Union Army during the American Civil War (1861-1865). It was a system primarily used for flag signals where there was a line of sight or for encrypted morse code messages.


Note each disk has a unique serial number as was used in the original wheels. Instructions for use are included.


The letters A.J.M on the disk are for Albert J Myer, the inventor and Chief Signal Officer of the Union Army. His system was called Flag Telegraphy or “Wigwag”.

Customer Reviews (4.8 / 5 · 5 reviews)

Sophia ★★★★★

The laser engraving on the wood is way sharper than I expected, and the disks spin smoothly without sticking. I've been using it to teach my kids how actual Civil War messages got scrambled.

Adam ★★★★★

I picked this up for a Civil War history unit with my students and it works exactly like the original field cipher. Spinning the inner disk to line up the letters makes the whole encoding process click for them way better than any textbook diagram.

Carter Q. ★★★★★

The laser engraving on the wood is crisp enough that the letters haven't faded after weeks of use. I've been using it to teach my kids how Civil War officers actually scrambled messages, and it works exactly as it should.
