I know there's not really been any advancement on this part identification, but I'd like to at least establish another research thread.
So far I've searched through:
- Old/vintage water pumps (caps/plates/seals/covers)
- water "tri-gate" covers, but probably too small
- Knockout plugs/seals, general and aircraft search (closer to what it might be)
- aircraft Instrument gauge backplates or covers
- vintage candy cans, containers, cases
- Rolls Royce aircraft engines (sans merlin and gremlin)
- WW2 Era aircraft parts
- Battery holders (like for watch battery sizes)
- Medicinal purposes
- Spring retaining cap/cover
- Transistor holder/plate (of some kind)
- Norelco/phillips razor related searches (unlikely as the packaging has been flat or open and these would more than likely be too large for this piece)
Probably a lot more than I can actually remember.
I'm at the point now where I think it's better suited we focus on the probable function that this piece had. It's clearly formed to cover and or hold a 3 piece circular object. I'm still leaning toward something mechanically related.
Too add, I think that since it has a large-outer "lip" suggests to me that it's placed into a slot from the inside-out, leaving that formed 3-circle detail to be exposed
Alternatively, I'm curious to identify what the technical process or name is for adding this notch is? I think identifying that aspect of the part would push us closer to discovering it's real function, as perhaps that added feature is served for a specific area of industry.

Anyone got any ideas?
