Chris,

In the winter edition of AGCO Advantage, there was a 1/2 page article about AGCO storing parts in a cave just outside Kansas City. The manager of the underground warehouse is George Campbell. George started 37 years ago with Oliver in Minnesota. I would say George would have a wealth of knowledge and would be a great possibility for a more indepth article for the HPOCA mag or a great reference for the mergers, experimental models, etc. Just wanted to let you know about this in case you ever had the chance to catch up with him.
