Artillery Round????

[Trentonfrank]

Found this today. Came up as a solid 99 signal on my AT Gold. It weighs about 2 or 3 pounds and has some writing stamped in it. Some of the engraving is corroded off and these are the numbers and letters i can see. Keep in mind I am not 100% sure if these numbers are accurate due to the corrosion, but heres what I think they are: 250 2DR N0 469208 LOT NO 98

Hopefully someone can help. Thanks for your time.

maybe a underground boring tool - called a bullet
used to bore under ground for new pipes

it's a nose cap for a dummy or practice artillery shell or possibly a large mortar round. what is the diameter of the threaded part? also if you can get any more numbers off of it or confirm those are correct I may be able to id it

It may be the "cap" to an artillery projectile, because projectiles are sometimes marked with a "Lot Number." Please use a digital caliper to precisely measure the object's diameter at the widest place -- the lower end of the "nose" just above the threaded section -- and tell us the result. If it is from an artillery projectile, its diameter will match up with one of the known calibers of artillery projectiles.

The markings being written in English indicate it is either British or American made.

Of course, while you're off huntng for a digital caliper, somebody might show up here with a convincing correct ID of it as something totally unrelated to artillery. ;-)

I see NOLA_Ken and I were typing a reply at the same time. He types faster than I can.

Thanks guys. I will have access to a caliper on Tuesday when I go back to work. I'm really curious about the age of this thing. I found it in an area where projectiles shouldn't be found...at least I never in a million years would have thought I'd find military stuff. Also, could you guys tell me what its made of? Like I said, it rang up as a solid 99 on the AT Gold and the metal in the corroded area is the same color as the non corroded area. It a greenish color. I figured if it was steel there would be a lot more corrosion and the typical reddish brown corrosion. Thanks again for your help.

Most likely bronze , people assembling shells did not like anything that
Would create a "SPARK".

Had a conversation with a Docent at PAASM. All assembly tools were
Brass , when they got damaged they would put them in a box.
Someone would melt them and recast back into new hammers , wrenches, etc

I was thinking 60mm mortar but it looks too heavy for that.

In the photo, it looks like it's made of a grey metal. An artillery projectile's "nose-cap" (a.k.a. ballistic cap) was made of zinc or aluminum or steel. If this object is made of bronze or brass, it is not an artillery projectile's cap.

AFTER-POSTING UPDATE:
I should have mentioned, when I enlarge the photo on the right, the corrosion on the object looks like aluminum or zinc corrosion to me, not bronze or brass.

Please make a small nick somehwere on the object's rim, and tell us whether the metal is grey/silvery, or some other color, like yellow (brass/bronze) or VERY pale gold ("white brass/bronze").

Not always, there are a lot of fuses that are brass as well. Especially naval fuzes which need to be resistant to salt corrosion.. Here's a British timed percussion fuze with a brass body.


A lot are made of other metals though, zinc and aluminum are common as well

Didn't the first paragraph of my post above make clear that my mention of the various metals was speaking ONLY in reference to artillery projectile caps? Not fuzes.

 

[Trentonfrank]

Thanks CannonBall Guy! I nicked the metal a little and its definitely silver colored metal underneath. I appreciate your knowledge!

Ah yeah, sorry.... I should have caught that but I was having my hair done by a two year old, and was a bit distracted....
