It didn't look like a Chestnut to me, let alone a Prospector (decks are not Chestnut looking, no seats, bow profile didn't look Prospector), so I asked him about it via the eBay send the seller a question section.
He said it was his grandfathers canoe, he doesn't know much about canoes, so he checked around and he thought it might be a Chestnut Prospector, so that's what he labeled it as in the add. I asked if it was fiberglassed and he said it was canvas covered.
I don't think it's a Chestnut, but I could be mistaken.
