The case bottom is busted on every one I have ever had shipped. It was put in as the case was assembled as it fits in a groove cut in to all of the other pieces. It is very thin veneer, about 1/8". The 4 other pieces of the case are glued and dowel'd together. Unless the case is very dry and falling apart all ready, it will likely be difficult to disassemble. I still try to get pictures of how it all fits together, as I seem to have a bunch that are apart.
