I remember when I bought my first large format camera, and 8x10" Gowland Pocket View on eBay that I still use (I also had a 4x5" version for a few years), and I had to order an extension rail and a few lensboards for it. I found the address online and mailed a letter, and a few days later was shocked when Peter Gowland himself called me in my office to check on the details. Since then we've occasionally been in touch by e-mail. He always loved to talk about his cameras and to find out what people were doing with them, and was eager to offer advice to younger photographers like myself.
I once called for info on his 4x5 aerial camera and was surprised when I ended up speaking with Peter. Even after it became clear that his 4x5 aerial wouldn't fit my needs, he was happy to spend time discussing aerial photography in general. Like Mike says, a real classy guy.
