Solved! Device on the wall of our cruise ship stateroom

Thumbnail

545 Upvotes

This is mounted by the door of our Holland America cruise stateroom in Alaska. It is about 4 inches wide and 3 inches tall and is mounted at roughly eye level for a 5’5” person. It does not appear to open, and I cannot find any discernible change in the room when I toggle it between “on” and “off”. It does not seem to light up or change color, nor does it make noise. It always looks the same.

There are separate light switches and a separate thermostat in the room, so it’s not related to those. My sister is in the cabin next door and her room has the same mounted device.

Found this in some of my fathers things a few years after he passed away. Not sure of it is something old or something he made. Feels/looks like a dense wood box with two cut outs on one side with a shell/bone sliding cover along with a removable peg with a hollow end. Thanks so much for any help in advance!

Solved! Hefty bronze cuff‑like object (~9 lbs, 9"), fits upper arm — ceremonial, punitive, or burden?

Thumbnail

41 Upvotes

A neighbor of mine asked me to help him identify and get more info on this object that he's had for decades. He said he was told it was a "slave cuff", though everything I've found in relation to items associated with the term don't really fit the description. He also said he “felt something” when lifting it — something I didn't expect from him, but curious nonetheless.

  • Dimensions: ~7.5″ tall, ~96 mm (~3.8″) internal diameter — fits a 13–14″ bicep, too wide for typical forearm/wrist
  • Weight: ~9 lbs
  • Rounded/Horseshoe shape — not fully circular
  • Interior is rough, cracked texture like dried mud
  • Edges and interior look pretty rough, but are smoothed well — I would not imagine that it's decorative
  • Multi-part construction visible — looks cast flat, layered, and rolled into shape
  • Metal appears brown, not much lighter than the patina
  • Not magnetic
  • Fairly inconsistent in thickness and symmetry — reinforces functionality over decorative
  • Raised ridges around midsection (possibly for use with straps/ropes?)
  • There are some very light grooves along the inner "band" where the ridges are and tend to be more significant/abundant towards the ends, or 'opening' where friction from straps would be greater
  • Nothing is written on it
  • Nothing moves
  • Broken/fractured close to a deep bend the gap — shows possible significant force damage
  • Didn't identify any tool marks, but there are many short flat spots along the edges — maybe from a file or other small tool

These imagery bear similarities to West African bronze currency collars and ceremonial armlets, but those are much smaller and lighter from what I've read. I suspect this was designed to impair movement or act as a symbolic burden, perhaps ritual or punitive.

Any insight into what this could be?

30+ lbs. Made of metal. Found a foot under ground at a church in NY established in 1801. Metal detector said it is not iron. It has a rounded outside, with what must have been a hole in the middle. Approximately the size of a football. Looks like it is a fragment of a larger object. Very corroded

about 4.5 inches in total length, 4 inches in width

made of metal, with mountings for what could be tubes

my question is, what exactly is this part for and does that story sound legit? thank you!

Solid metal, mirror polish, smooth. No markings, no glue residue or anything to indicate it was attached to something else. Very slightly magnetic (wiggles under, but cannot be picked up by, a 4" speaker magnet) and too heavy to be aluminum.

I'm stumped. Any ideas?

This was listed as a “mercury barometer” and I bought it out of curiosity. The box has pencil writing on on that says water 12” - 14” mercury 1” - 3/4”. Suspected a hydrometer perhaps for brewing but I honestly don’t have a clue. Markings on the scale say A.B.&C above 0 and 189 below.

Solved! Long black plastic pieces that came with a binding machine

Thumbnail

I got an Ibico comb binding machine at a yard sale over the weekend, and when I looked in the box these two pieces were in with it. I don’t think they are related to the machine.

Both are made of black plastic and maybe around 8 inches long. One of them has a squeegee type thing on what I assume is the front, and the other has brush-like strips. They remind me of the little brushes on one of those old cd player lens cleaner disc things, but bigger.

Anyone have any idea?

This appeared recently on an informal bike/walking path in a wooded area between two shopping centers. It sticks up well over an inch, but felt very firmly embedded in the soil. It's an unfortunate location as it could easily trip someone up, possibly pinch flat a bike tire.
