It was obviously not a Parrot shell. What it was/is is anyones guess.
All anyone has to do is send the guy a message and tell him he is mis-representing the item or tell ebay. The links are there. Had I seen the listing I would have done it even though I wasn't interested in the item just to keep a neophyte from getting bitten.
I would purchase artillery shells from ebay as long as I have good photos and an explanation of where found. That gives me a good idea if the person knows what they are talking about.
I don't want someone to tell me they found a Sawyer at Mansfield, La. Ain't happening!
Some people are interested in fragments, I'm not. I did however sell a Sawyer fragment, a nice burst fragment with the flanges on it, on ebay for a friend of mine. It came from Port Hudson.
You just have to know what your doing before ya do it.
