Indeed, Sir

Thanks! If it helps... research can be fun. If you have a good library take advantage of it. The Internet is a great source, but it can be limited and frustrating {sometimes just a difference in search terms determines whether the info. sought is found}. Sometimes my research makes me cry-watching London be bombed, for instance, but it can also be a very enjoyable process.
Best wishes and if I can help in any way, let me know.
