The parts that Everlast specs do stay the same, and are pretty well documented. But many parts are selected by the factory and often change lot to lot and have little to no documentation. You could try to keep a list, but then people would count on it and when it's wrong they would complain.
For example Everlast specs a regulator/flowmeter that is CGA 580 in and 6 or 8mm hose barb out. Those specs always stay the same, but there have been quite a few different versions of this one item with different threaded fittings connecting all the different parts together. Each supplier is free to use whatever and often will change over the life of the product.
Older machines used to be spec'd with a hose barb inlet. Now they have changed to a threaded fitting that is standard across the line, so that is nice.
Some things are designed to be user swapped and follow a standard. Things like DINSE plugs and such. Other parts are supplied complete, but not subject to standards as long as they work. Like if you want to change the DINSE connector on the front panel. Sure it's DINSE on the outside, but where the wire attaches it could be another connector, a threaded stud, a tapped hole, what size, what thread? It doesn't matter unless you are doing that repair/upgrade, then it is up to you to make that decision.
Long arc, short arc, heliarc and in-the-dark!
