This one passed the magnetic test and did a file test to see the window. Weighs about 10 grams. Would like more advice on where or who to take it to, to get further testing. Thanks.
I usually take my 'possibles' to the local natural history museum, I'm 0 for 10 but I always keep looking. Most of what I have found is natural metal deposits or slag. This one looks like you should investigate further. You can always diamond saw it and etch it with Nitric acid and look for the Widmanstatten pattern.
