Well, they are a pretty narrow field, so they won't fit a lot of bases, and for somebody to have a base for it, or to find a base for it would be difficult. IMO, if you can't thirty dollars out of them I'd let them go. Thats why I won't buy anything unless its all there. UNLESS, its something pretty rare. I have got pieces that I have had for years waiting for a piece to come along and make it whole. Looking of course is part of the whole collection thing though.
