The first indication is tha with no reserve and only 6hrs. to go the price is still at .99 cents and it is listed in the civil war section.
No 9"dia. iron balls listed in the Ord. manual so I don't know where he looked up the info.
Mortars did not shot solid shot. Shells are hollow.
Were it real, $300.00 or more.
May be some kind of machine part.
