Inverter Pump Question

I found a prius with the inverter pump and thought id take it if they want like 10-20 bucks BUT only f its original (OEM) Aisin or Denso but I dont see any Aisin or Denso stamps on it so wondering if it should show them on the actual pump, if so then I assume its aftermarket and wont take it.

Id want it to carry it as an emergency in the tool bag.

If anyone can confirm this question and even better if they have a photo of where the markings are if any would be greatly appreciated.
