Can you explain what these little clips might be 4 gas planets

While I’m thinking about it, the mystery clips resemble a furniture clip I’ve seen, but not close enough to be definitive. I’m also being (highly) speculative here: The clips I’m thinking of would have been used to retain a cover (usually wood) in a frame (also wood). Think of a dressing table with a mirror in a frame. The mirror is held in place from the back with a piece of wood the same size as the mirror. The piece of wood protrudes from the frame in the back. The clips engaged the edges of the piece of wood. The screw in each clip allows the piece of wood to be snugged-down to hold the mirror tightly. The second hole is for a brad to keep the clip from rotating.

To install, the screw hole is drilled first and the screw run in part way, then the piece of wood is put in place to hold the mirror, then the clip is rotated into position with the teeth biting into the edge of the piece of wood, then the brad driven in, then the screw tightened down to finish the job.

To remove the piece of wood, just remove the screw (using what for a screwdriver?) and pivot the clip on the brad, which is left in place. In an emergency, pry up one edge (bending one clip) and pull out the piece of wood to get to the mirror.

There are some things I don’t like about this concept. There are only two clips, and each is different. For a commercial mirror frame I’d expect 4 or more clips, and all the same. What sort of "mirror backing" would only need two clips, each a different design? A quite small mirror? What sort of thing would need retained by screws that must have been in pretty thick wood, judging by the length of the screws? The screws and clips aren’t decorative enough to have been on the "front" of a mirror used by anyone with good taste, unless they were covered or out of sight somehow, implying the clips were on the back side, or inside, or otherwise out of sight, or simply utilitarian.

The association with a strap retainer isn’t out of reach, either. The shape would be OK for holding a strap in place and resisting rotation, hard pulling tension with the screw in shear, and modest pulling that loaded the screw outward. Again, the combination of the teeth, screw and (assumed) brad hole make it clear to me that the clip is intended to resist rotation. What does this describe? ‘How about a strap that prevents a hinged box lid from opening too far? The clips are mounted at angles inside the box, and the teeth keep the strap aligned so it is nice and flat when the lid is open. The box wall would need to be thick enough for the screw, implying a rather heavy box. This also implies hinges, a latch and maybe handles. What else might need a strap that limits motion?

The bent clip was explained elsewhere as evidence of forced disassembly, which I agree with. It’s easy for me to imagine a lid that has been broken off of a box, but still has the strap connecting them. A hard pull will pull out one clip, bending it. Then again, I’m imaging things about a clip that has no definite purpose. It might be for some other use. I’d like to step back a bit and ask some rhetorical questions:

‘Lightweight’ is appropriate for aircraft use, but the long wood screw implies thick wood attachment. That limits the aircraft applications somewhat. Lightweight is also appropriate for hand-carried things, like luggage or instrument cases that are used in the field. I found a wealth of antique custom-made gun cases, on the web of course, with lots of hand-made bits and pieces, for one example.

‘Non-rusting’ assumes ferrous alternatives could have been chosen instead, but weren’t. What ferrous clips (painted or coated with zinc) were like these? Rust stains fabric, so aluminum might be picked for use as a fabric-retainer, rather than something that rusts or corrodes (brass or copper, given long enough, will stain fabric with verdegris).

‘Easy to fabricate’ argues for local fabrication (native use), or limited tools (also native), or cheap manufacturing requirements. Aluminum would be one of the few materials a native artisan would be able to work from aircraft parts, or aluminum ship parts, or aluminum from any source. What tools did locals have? tin snips, files, saws, drills, torches, machines, CNC? I’ve seen amazing work done with a file, hacksaw and patience, but not on cast iron or heavy steel engine parts, which might only be useful as an anchor or anvil.

‘Electrically conductive’ is an intriguing property, bringing to mind a grounding/bonding clip. The teeth would bite into the thing needing to be electrically bonded to. No application comes to mind that would require bonding yet also use a wood-screw. Did a wire somehow connect to the little hole? Aluminum tends to corrode easily when used as a conductor. Anyone got other suggestions for electrical uses?
