I apologize for trying to help out others who might be in the same situation I was. Why would anyone even do that?
I wasn't asking how to find the information, because I already did so. I was offering a suggestion to others who might be similarly challenged.
I agree that posting the listing for an item that's baffling might also be a good approach, although my searches for this item led me to a number of dead requests in various forums on similar things, so maybe it's not a perfect approach.
