Stevenotts, do you just have the module, or do you know what it came out of? (The manufacturer of the rig?)
Is it foreign or domestic?
Anything you know that we don't, might help.
It's possible the QA1 124 is just some designator they use in the factory when they're
assembling the finished product. It might have another number engraved or taped to it that might give more useful information for identity purposes.
