CB53 - no ... I hadn't got that, either. Thank you so much!
SpoonerJ - do you want to see what we can do on this one by putting our heads together some time, and see if we can make a bit more progress? I'd certainly like to capture that family story of your in my notes and get as much detail about it as I can.
Drop me a PM message if you think there might be some mileage here.
