Berdan cases are de-primed from the outside. Usually some kind of poke it-- pry it--push it monkey motion, none of which works really well. Another method is to hydraulic them out, using water and a piston. Messy on a good day.
I have seen new manufacture brass shotshell cases for sale. Italian IIRC. They were all Berdan primed.

1129: It's a roller. Probably you put 4 of them on a wooden frame and then you could roll the frame. 1130: Some sort of navigational instrument, perhaps for taking sun or star sightings. 1131: Manure stirrer.
1132: Sometimes a spade is not a spade. Entrenching tool, though, before they came up with the folding kind?
1133: Appears to be a sprinkler of some sort.1134: Leather punch
1135: Perhaps some sort of pressure gauge.
Well, here's what I got. Don't know what any of them are called:
1130 looks like some sort of optical device. Some kind of viewing instrument, perhaps? For measuring things?1132 looks like it might be for cutting or chopping something, like a chisel, perhaps?
1134 looks like you could use to punch a hole in something -- put in in there, squeeze the handle, and the spike drives through it.
I found this one in a box of gun related items, I don't know how it's used but it looked close enough to the tool at this link that I figured they were for the same purpose:

When squeezed shut..the chisel jams deep into the Berdan primer and as you open it..it rips out the primer cup

Political Correctness is a doctrine fostered by a delusional, illogical liberal minority, and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.
The link below has some photos of an aluminum torus that someone found in their father's workshop after he passed away. I've heard some guesses on it, but haven't been able to verify any of them, maybe someone here will recognize it:

What was the background of the Father... That could be anything from WWII part of some sort to a XRAY machine or anything. Sometimes Goo is flux, grease, or special chemical for a unique property that isn't plain to the causal viewer.

Let's see. D is the diameter from the middle of the tube on one side to the middle of the tube on the other side. That would be (15.2 + 45.2) /
2 or 30,2 mm.d is the diameter of the tube, or 15.2 mm.
Volume is 2.4674Dd^2. That would be 17.2 ml.
If it were solid aluminum it would weigh 45.4 g.
4 ounces is 113.5 g. That must be some very heavy paste.I wonder where I went wrong...
I had asked him that question, here is his response:
"My Father, after retirement, had a small work area in the garage, mostly for puttsing around with lawn equipment and his car maintenance. How or why this object was there is anybody's guess, he did not do any precise work....he was a life long salesman."

What volume do you calculate? Is it really 113 grams?
He must have meant about 4/10 ounce (11.3 grams).
It looks like a very precise, reliable hydrometer.
You put it on a scale and adjust the ballast for the desired weight. Then you drop it into the liquid. When it shows no tendency to sink or rise, the liquid is at the desired density.
The clip would make it easy to check the displacement with a scale. First you'd give the donut enough ballast to sink in water. From the scale you'd hang a length of thin wire with a loop on the end into a container of water. Then weigh the donut on the scale with the end of the wire hanging in the water. Then clip the donut to the wire and weigh again with the donut submerged. That will tell you exactly how much water the donut displaces.
You would adjust the ballast to get the density desired for the liquid you wanted to test. Paste would make good ballast because it wouldn't shift, could be added or removed in tiny amounts, and, if insoluble in the liquid being tested, could help seal the donut. To measure really dense liquids, lead shot could be added to the paste.
The tubular shape of the donut would resist compression, which would make density measurements imprecise. The hole would allow you to use a string to pull it out of a tank without having the string affect its buoyancy; on the end of the string would be a metal washer too big to go through the donut. The washer would be on the bottom and the string, passing through the donut, would be tied above the suface.
It could be used in a research lab or as a gage for a particular liquid such as antifreeze, oil, brine, or syrup.
Mine came out nearly the same as yours, so I guess he's got the weight wrong, I'll ask him about it.
Rob
Thanks, I'll pass this along to the owner of it and see what he thinks.
