Finally, through the magic of the Internet, I found one! So what's the big deal? Here's the designer item that came closest before I found the one. On eBay, it was $1700, used. Welllllll, I don't need an extra $1600-worth of name (Prada), ever. Drat, keep looking.
Thanks to eBay, I've ordered one that I like even better (nicer neckline and beautiful medallion back), though I took an unusual risk, at least for me. I made an international purchase from...Malta! Thoughts of Knights Templar fill my head. Once it arrives, I'll let you know whether it is a good thing to engage in commerce directly with the Maltese.
Sounds like my own Bogart movie in the making,
just a few decades too late!
