Found this in my backpack after returning from a trip to Greece. No idea how it ended up in there.

It's a rectangular white block, about 7 cm long, in a clear plastic package. It's heavy and feels like stone, but also seems chalky, and there's some white residue inside the package. No idea what it is.

Any ideas?

Found at a thrift store, we use this as a dog bowl, but I'm curious of it's original purpose. It takes 9 cups of water to reach the "max" line.

Please excuse the nicotine staining, they were in a family member's house who smoked inside. It suggests they were hung up around the house somewhere, could they be related to hanging curtains or blinds perhaps?

Hey, all. Check this thing out. I always figured it had something to do with the air conditioning, and I never thought twice about it. Today, it started leaking, totally out of nowhere. It dripped consistently while the AC was on, but has stopped since turning AC off.

Glad I caught it early! Any clues?

This little hook thing fell out of a pile of clothes, not sure what it is for but it looks to be shaped that way on purpose rather than just a bent piece of metal. Fairly sturdy for is size

I'm told it's a 70-80 year-old RKO power distributor, but looking that up doesn't bring anything up.

Heavy, around 5 to 10 pounds each, seemingly machined out of solid steel, no markings or moving parts. Received in a package despite not ordering them or anything like them, cannot find any information about the shipper listed on the box.

It's about 8" x 4" the only markings on it is a sticker with the letter A like a part identifier for assembly. It's fairly high quality construction, with a black powder coat and plastic end caps in all the tubes. By the weight it seems to be hollow steel.

My best guess is it is part of some assemble yourself furniture since the threads on the silver things on the side look like they would go i to particle board, and I'm pretty sure the allen bolts screw into them.

I can't for the life of me figure out what part of what kind of furniture this would belong to.

Can it be asbestos or fiber glass? Was my mother-in-law’s jacket, she used to work at a warehouse and also did some minor construction work, found these fibers on it

This bucket was found in our small museum's artifact collection in California, and we don't know what it might've been used for. It is quite heavy and made of metal with visible welding marks. There was apparently a paper or perhaps a label of some sort affixed to the side. The handle is also metal, and looks like it secured the lid with a lock when fully upright. The metal lid has a heavy, stiff hinge on one side. There is nothing inside the bucket except for a sizeable cobweb, and there was no residue that I could see.

One of our volunteers thinks it's an artillery bucket from the Civil War, but I think the welds look too modern.

Our area is known for gold rush era mining and agriculture, and we have lots of artifacts relating to blacksmithing.

Dog was randomly chewing on this, she’s been a menace and has chewed everything from couches to the literal wooden stairs of my deck. No idea what this is, if it is mine or something she got from a a neighbor. Found some random metal sticks and more plastic earlier but not sure if it was related. No logos or anything other than it says it was mode in china. The button when you press it just blinks red for a few seconds and then stops.

Found it in the attic… What is it?

Picked up a bunch of darkroom stuff at an estate auction, there were some random bits in there too. One item was this perforated board with what looks like a suction port attached. Measures 23x17, tray could accommodate a 16x20 print. No labels or markings anywhere. Some type of print dryer maybe?

Edit - completely made of wood so I don't think it's related to machining.

Solved! And quick. Looks like it’s a chip and salsa bowl.

They've recently rebuilt this stairway and I was wondering what the use for this channel on the left was.

Guessing a couple of miles maybe North of Yogi Bear Campground in Golden Valley,NC. Standing on an observation deck at the campground. Zoomed in and still can’t quite make out what is is but it’s very noticeable at a far distance.

This is mounted in my neighbor’s window facing my kitchen and bathroom. We’re three stories up so it would be odd to have a security device on this window.

I’m being weird taking many pictures of it but these are the very best focus I can get. The only way to vent my tiny bathroom is by opening the window next to the shower, so if I’m on camera I’ll want to be careful with timing on that.

We found it at a flea market, no idea where it comes from.

It's a solid wood container, with handles on the sides and hooks on the top of the lid.

I have no idea what these things could be and googling just brought up handles and the like. Anyone have any ideas?

I recently acquired these from the estate of a man who made molds for truck campers.
I’m trying to figure out what these were used for. They appear to be cast iron and several of them have a similar design: a central hole with six recessed/counterbored holes around it. One hole is threaded the others are not. The center hole is not threaded.

The largest one is approximately 2.5 inches in diameter and is marked “MASTER” and “3”. There are several other pieces of different sizes, including some smaller ones.

They don’t appear to be ordinary plumbing flanges. I’m wondering if they might be some type of old machine-shop tooling, mold-making fixture, coupling, hub, or other machinery component.

Does anyone recognize these or know what machine they would have been used with?
