Jettore: yes, I saw that thread but kept seeing references to "this guy told me to call that guy..." and then when the call was made the guy who knew him had passed on.
However, I note something I missed before and that's the Yellow Book entry. I think I'll either call or post a letter this week and drop him a friendly line
Always nice to get info straight from the horse's mouth... I'll update if/when I have more info.
