At least with the posting to Rec.crafts.metalworking. Most
people here will have a pretty good eye for handedness on threads. :-)
Probably the woodworkers, too, though I think that left-handed wood
screws are pretty uncommon. :-)

And they probably used a desk ruler or a tape measure, so
getting a reading that accurate would be pretty unlikely. :-)
Well ... brass and bronze look very much alike, especially when
clean. They develop somewhat different patinas, but the real thing is
strength. A tool should be bronze, not brass, and I would be willing to
bet that this one is bronze. If anyone could track down the logo on the
handle it would probably show up listed as bronze -- maybe phosphor
bronze, or maybe even Berylium Copper.
beer through? I would have expected a series of small ports between the threads.
I think there is a hole on the other side near the tip of the screw, I should
have taken some more photos but was in a hurry at the time and just took a
couple of shots.
The person at the military blog agreed that 2950 was a projectile but hasn't yet
given more information about it.
My answers for this week have been posted here:
BTW When you need help with answers to some, could you please
include the number(s) (e.g. 2433) instead of saying "the fifth
from the top" or "the second and fifth"? Given how far apart
you space them (at least as seen on my browser), it is easy to
lose count when scrolling down from the top -- especially if the
scrolling is somewhat jerky, which can cause me to skip over one
2962 - I recognized that pry bar end, but the other end was different.
We called it a Halligan tool and it was carried in the trunk of a police
car. The other end had a 90 degree spike for cutting holes in things.
2950: The M256 is a smoothbore gun used on the US M1 and M1A1 tanks.
The bore is 4.7". It's a version of the German Rheinmetall L/44,
meaning the barrel is 44 calibers long. I wonder if this could be a
practice round, dug out of a berm at a target range.
2947 - Wine tap?
2948 - Valve lapping/grinding tool
2950 - 4.5" shell for large gun.
2951 - Tubing bender.
2952 - C6 multi sledge, another of a long line of "improved entry tools"
made for police/fire use.
Just a wild guess:
I think this could be a foundryman's crucible for metal. The marks around
the periphery tally with the use of tongs in handling.
I don't think it's ordnance. It appears to be cast. Cast is relatively
brittle. If it were a shell head, why would there be casting marks on the
base? What would prevent it shattering in the barrel of a gun, especially if
it were packed with explosive material?
Could be a mould for something such as 44mm shell heads, if such a thing
I'm not much into ordnance.
