Your diary sounds like a great piece of family history and would make for interesting reading.

Like a lot of eBay sellers, I sell the stuff that interests me. I have been fortunate to be able to build a good little business that handles some interesting things at times, most of which I would never come across if it wasnt for selling on ebay. I also get to meet some interesting people I would never meet otherwise. Often these are international buyers with similar interests to my own and it is  selling on eBay that provides these opportunities.
