Rob,
Thanks for your response. It is only with
patience, and politeness added to our natural inclination to "need to know" everything; it just
takes time.
None of us know anyone who knows all the answers, philatelically speaking. She or he would be much in demand if that were the case!

Myself and countless others online await the results of the O.P.'s questions.....
