Xmags have had valves exchanged before as well. A valve is just a valve. It can go into any mag. Its not the valve that makes one mag different from another. Its the body and frame it is installed in.
Most people don't part them, and if they do, its easy to find the serial numbers in the list if they are alphabetical/numerically listed. It is up to the current owner to list the valve in the proper place and remove it from any other existing location.
You don't want to track all mags by their iterations. You only want to track the valves. If its not an emag, it should only be listed by valve.

Except for the Automag in front, its usually the man behind the equipment that counts.
