We've had some discussions in the past of some unusal fasteners on various coach bags including snaplocks, spring closures, and turnlocks.
My suede fringe dinky 86821 has a rather unique turnlock construction that I don't recall seeing on other coach bags. It operates like a regular metal turnlock but it has a leather-covered center piece that can fold down - I guess it acts as an extra "security" lock?
You can see a picture of it here and there are more photos at the link below. Has anyone seen a similar style turnlock on other bags? Do you think that my guess is right that it is supposed to function as a security lock - or maybe it is just a bit of extra decoration - or both?!

This is such a pretty bag! I want to say I've seen a similar turn lock, but I can't place it. I can't see how the tiny piece of leather is enough of a deterrent to keep the turn lock from being turned or the flap from being opened if it is turned. I think it's decoration just based on the decorated plate around it.
I think that it is a small metal lever that is covered with leather, below is a before rehab picture of the turnlock; but I agree that I can't see a practical function for adding the lever, so it is probably just a decoration.
