I found this in the yard of a mid-1800's farm house. It's about 3.25" long x 1" wide.
Came up as a solid 65 on the AT-PRO and a 12-28 on the e-Trac. It looks like it might be silver plated. It has some fancy on both sides. It may have been tubular at one time before it was smashed flat. My first thought was a lipstick tube but I think it's way to big to be that.

Not heavy enough for lead. Only weighs about 10 grams.

Tubular long ways??
If so I would say it is a pen tube shaft missing both the writing tip and a cap on the other end.

I would say it's to wide to be a flattened pen tube.

You know how to calculate pi squared. Actually it would be .637" instead of .640 but we won't squabble over a mere .003 " If you were to drill a .640 hole ,you would want a 41/64 drill. or 16.256 mm for metric conversion.
 
:lol: I knew what it was, just wanting others to consider it's diameter prior to being flattened, if in fact it was. I couldn't even venture guess as to what it is/was.

Since we had only one significant digit in the original measurement (1 inch), it's meaningless to carry out the calculation to three significant digits. Actually even two is one too many.

Maybe I got a little carried away but often the forth digit is required for my job.My job requires tolerances of .010", or only .005" depending on which part of the process the product is at and now often +.000/-.003" In the original post,the third digit was rounded up to the nearest thousand of an inch,which is .0003" more than actual dimension.:roll:
 
Here is a pic of a lighter case ... recovered at a park in Americus GA

Not silver in my case but a neat find

Now come on guys, you are making me remember why I failed all those math classes.:roll:
