Came across a really cool tubular lock today.

At first I thought it was some model of Fichet, but it's a tubular lock with the bitting on the inside of the key.

@alice Nice! I'm not even sure how you'd tension that beast. 🤔

@jacklund I suspect it tensions off a disc under the outer ledge that interacts with the tab on the nose of the key.

Either that, or it actually tensions off of the center hub, which would make it easy.
