I'm wondering: did Petz & Lorenz, who made the so-called "Intermediate Spange" (a misnomer, by the way), ever make a 1. Class Spange in tombak? I know reference books say they did, but does anyone actually own one they can put a magnet on to satisfy a nagging question in my head?
Thanks in advance for any help.
