The cage looks like a Jail Bird. The Prince Albert lock looks like the first result you get when you search for a "prince albert lock". However, the ring around the glans throws me. Is it part of the cage? Part of the lock? Used in conjunction with the lock (since the cage itself doesn't have a cross bar, meaning that lock would only work if it's bigger than the gap)? Just a random ring for aesthetic purposes? Hope you can help. Thanks.
