While this thread has posed an interesting question that still must be answered... I have some update info.
I queried the seller and this was the answer to my question about how many patches were available for purchase:
Subject: Re: Question for seller -- Item #3651902061
One--the one that"s listed now.
So now it appears that the shop that made our patches has sold off, or tossed out some of their samples and this seller acquired them and is selling them on eBay... so the appearance of more of these seems unlikely...
...that being the case, anyone who wants the one patch that is available on eBay... Bid Away! and good luck.
OTOH, I learned this afternoon that one of my professional colleagues has a daughter-in-law that IS a copyright lawyer and he volunteered to ask her the questions we have posed and get us a legal opinion about what rights the forum has about someone selling our patches for profit... and the legal advice will be at no charge
As soon as he has a reply, I will post the answer.
