Thank you for all the kind comments.
Unfortunately, this find seals the fate of my Azur speedy. I have not carried it but a handful of times since getting my Beige Clair GST last year and then I got my Siracusa two weeks ago. With this ivorie handheld, there is no place for the azur speedy, but I believe I have found a good home for her.
I agree that screwbacks are the only way to go. I never take my earrings out so I need them bolted to head.
