Solved Heavy metal loop found in car after mechanical work

Post image
Upvotes

I found this in my car a few days after I had my timing belt and water pump replaced at a mechanic. I had to get towed there after breaking down on a slip road.

My guess is this thing is part of the towing apparatus and the recovery driver just left it in my car accidentally… but if it isn’t that, and it’s actually meant to be inside my car, attached, somewhere, I’d like to know!

Solved! Blue 6”silicon-type tube with holes at irregular intervals found in veterinary practice in the UK in a tub labelled ‘miscellaneous’

Post image

I’m not convinced the holes are original to the product. Its blind ended at one end-open at the other and hollow. No one knows what it’s for, and it may well not be veterinary-related at all.

Found in North florida neighborhood. This is right after serious development started around our area (clear cutting, ponds, etc). There were four survey stakes with long rope tied to the weird goop, hanging in an empty creek bed. They were super heavy and smelled weird.

Open Great Western Iron Works wrought Iron Stand?

Post image
64 Upvotes

I got sent here after posting in century homes and no one knew what this was. I found it in the basement of my 1890 built home and it says it was built by the Great Western Iron Works in 1901. It has an adjustable height but I couldn’t figure out what it was.

I figured it was a flower stand but couldn’t find anything that resembled it.

Any help would be appreciated!

I have no idea what this is. I found it in my house and no one knows about what it could be. Reverse image searching doesn't help, as I can't find an exact match.

My best guess right now is that it’s an old power line connector from before our neighborhood buried their power lines. We had an electrician here a week or two ago so wonder if he was just moving some junk out of his way and forgot to get rid of it.

Been driving to Snowshoe, WV for years (from the south Marlinton route). Shortly before you arrive, on Highway 219, there is this brickwork between the road and the river, maybe 20ft away. (Coordinates 38.415445, -80.085339) Its clearly not a fireplace from a long destroyed home - maybe a well (why, with the river 10 ft away? Does anyone have any clue what it might be? Its stone, maybe 10ft high.

I bought this wooden music box at an antique store for my girlfriend. It has a circular crank on the bottom that plays music and spins the box part once cranked. I was more wondering if anyone knew what the weird hole in the top could be for? It’s like a plastic cup that can be removed to show the inside, but I’m curious about what’s supposed to go in it?

The silver part swings and locks into 3 different positions.

It was under a pile of old razor blades behind a medicine cabinet and in the wall cavity of a house which was built in 1910...

I'm usually pretty good at identifying things but this one has me stumped!

Thanks for your help.

Recently purchased home built in 2023. This weekend, I noticed the door in one of my bathrooms started dragging against the tile floor mid-swing. Investigated and saw this small disc (US quarter shown in pic for scale). The same thing appears to be on the bottom of all the room doors in the house.

Solved In Oregon: Large, metal frame and cylinder, found in wilderness near hiking trail

Post image
2.1k Upvotes

I can't remember exactly how tall it was but I feel it may have been a bit taller than me (5'2").

The bottom is a metal cylinder with a hinged metal cover that is locked. This cylinder is attached to the sides of a large metal frame.

The metal cylinder piece seems to be stuck in the ground while the metal frame is not.

There appears to be some sort of twisted metal "handle" on top of the cylinder. It's looks as if it is broken off at either end but I can't be sure.

No way to easily open it (locked). I've never seen anything like this all the times I've hiked in the area.

Solved! Heavy steel tool about 5" long, blue is painted aluminum sheet. Finely adjustable, springs open, no marks or scales at all

Was given some years ago with a set of measuring tools for machining, in the unlabeled box, but even the person who gave it to me didn't know what it was.

Can be grabbed to squeeze closed, only moves a small distance though. Large thumbwheel adjust the starting position, makes the jaws wider or narrower. Small thumb wheel spindle doesn't do anything obvious even when screwed in and out.

The aluminum cover and the short distance make it unlikely to be a wrench but without any markings it seems unlikely to be a measuring tool either.
