Eric,
I too have been keeping the photos of many sets, no way I could save all, I do have a question that you might be able to answer?
Many of these "sets" are obvious because thay have accompanying boxes and some are said to various manufacterers together, but many of the "Themed" sets such as Borodino or Sedan 1870 or battle of Leipzig 1813, were these first sold as a grouped set? or are they composed and put together by previous buyer/seller?
