There's a book called "The Heddon Legacy" by Bill Roberts and Rob Pavey, published by Collector Books (collectorbooks.com) that you might find interesting. The story is interesting and the photos and prices shown are jaw-droppers.
Well, darn. I just checked and they don't list that book any longer.
Second edit: Holy Hannah - the flipping BOOK is now worth over $200 on Alibris!
