I'm really chuffed at this piece of information
The thing is I had left this to one side to concentrate on other bits of information, but I'm just sat here with a big grin on my face, tears in my eyes, and dancing on the inside!
Just need to find the citation now. I know Tom's eldest son had it at one time, but no-one knows what has happened to it. With your information, I now have to locate it at least!
