	~~Add~~ to ~~me!~~		The principle security features are common to both the 14 and the 10 lever. They are:
			* Two stacks of levers that are operated in parallel. Both of these must be set before the stump will pass the true gates
			* The majority of levers have at least 1, if not 2, false gates.
			* The stump and the false gates are made in such a way as to lock firmly together
			* The bolt locking mechanism.

			It is the last of these that is reasonably unique to the NATO Mersey locks

	~~Add~~ to ~~me!~~		The 10 lever variant of the Mersey exists in at least three iterations. There are those early models where the lever pivot bolt is free to slide along a captive slot, in later models this slot becomes a round hole and finally square. The ability of the lever pivot is a key part of the bolt blocking mechanism.

	The lock has an unusual “V” shaped brass key (earlier models had a plastic key that was prone to breaking).
