Doesn't look like brass...
Brass can be green, copper, gold, brown..
But that looks grey, you sure it's not lead?
Almost looks like a crazy bullet..
<°)))>{
Looks like a plumb bob to me maybe?
Looks like it could be a screw on tip for a probing rod.
I did not know what a "probing rod" was, but I googled it. But would it have a brass tip? With that strange coarse thread?
I thought so too, but I have never seen one this small.
Those things that look like "rings" are threads? They are strange. It looks like it was very crudely turned on a lathe when it was made - not a terribly smooth transition and that sprue tip is odd too. What does the end that looks like something is broken off in it really look like - is something broken off in it, or is it all solid brass?
My guess would be a tip off something too.
Looks like a practice tip for an arrow (field tip)
. They are fairly heavy to simulate the weight of a full broadhead.
Exactly what I was thinkin
