黛安娜密碼系統 | 美國陸軍特種部隊密碼輪盤

The wooden wheel turns smoothly and the lettering is crisp enough to actually use for practice messages. I keep it on my desk and it's become a fun way to explain Cold War field encryption to friends.

I've been getting into Cold War history and this replica is a great hands-on way to actually try out the DIANA cipher instead of just reading about it. The wooden disks turn without sticking and the letters are crisp enough to line up quickly. Solid little piece for anyone who likes old-school trade

The wooden disk spins smoothly and the letters are carved deep enough to read in low light. I keep it on my desk and use it to encrypt short notes to my brother, who's into Cold War history. Feels like an actual piece of field gear rather than a cheap souvenir.
