I got these in an auction that I won. They were a throw in. They are smooth metal tubes. I think aluminum. I just have know clue.

 

Looks like the makings of pipe bombs

 

I guess I shouldn't mention the container of 5000 bbs that came with them.

 

Zamfir's pan flute? Is one end beveled/sharp? I was thinking hole punches of a sort.

 

I guess Zamfir accidentally included that in the sale of his Oldsmobile.

 

Both ends are rounded not sharp. They are numbered 0 to 9.

 

One end is cross hatched for gripping I guess

 

My best, uneducated guess would be some sort of gauge. For what? No idea, and I've never heard of 9/0ga. wire, so I doubt wire.

 

That type of collar allows you to put translational force on something while letting it rotate inside. Like a spinning handle on a fishing reel. Either that, or it is gauges. I think the knurling means a grip, though.

 

i have some old seal drivers that look like those.say for pitman shaft seals or front a/c compressor seals etc.

 

They are sockets for zero-point bolts.
These were promptly discontinued since they had a tendency to round off.

 

What is a zero point bolt? Is it an off-round bolt head?

 

I guess I should have put LOL after the reply just to be sure my intent was clear.

 

Ah, now I get it.

 

I did an image search and got all sorts of hits showing similar UXOs (unexploded ordnance) or shell casings.

I agree that they are some sort of tool though given their varying size and the way they're grouped together. The only other hit I got that was similar was for flint knapping tools:

If they are in fact aluminum they may be for ordinance maintenance/handling. No spark. Back in the early seventies I was a technician in the Navy repairing the Magnetic Anomaly Detection System. The sensor head was about six feet long mounted on a non magnetic gimble which in turn was mounted on a non magnetic frame extending it out from the aircraft. All our tools were bronze or bronze derivative.


Sorry but I couldn't find an actual image of the device but this is the housing that extended from the aircraft skin around the actual sensor. There were motors which drove the gimble on the three axis of aircraft flight to keep the sensor in alignment with true zero at the north pole no matter how the aircraft maneuvered. These motors (of course magnetic) were mounted near the base of the "stinger". All very cool stuff but old, old, old technology. All the amplifiers and electronics were tube driven. There were six boxes each about a foot and a half square weighing between 30 and 55 pounds each. The power supply was about 70 pounds, it had a huge transformer in it.

 

They are aluminum. I can see some sort of gauge. You can see faint scratches where they have been slid over something. I will throw them on a shelf. Then 50 years from now my kids will wonder what they are and then pitch them.

 

My father would hate these. He was on submarines in the sixties and did his best to avoid these.
