I am not knowledgeable enough about this subject to answer most of the standard questions with confidence.  I'm sorry.  If you have questions, please send me a very specific message about what you want and how to determine it.  Pretend you are talking to a 5 year old.

Look at what I have in my store.  You may be able to have me send more than one for less money.  Click at the top of the listing where it says "Seller's Other Items".  I am just beginning to list these - 10-2-25.  It may take me a while.
