Look's right to me , but I've only dug 'Frags' thus have only studied them.
I do have a Solid Ball or my Son picked it out at a raffle. 6 or 10 lbs.
As for location found , maybe a ' mass spec, scan ' that may match microscopic dirt or other particles to a certain area.?
We should have a kit for that in 15-20 years. (an affordable one ).
Honestly You really have to trust who you traded with about it's past.
Ill have to look at the one we have , don't know where it was found but will check the 'seam line' that look's right to my aged memory.
