Hi Christophe! I hope you find one! These have become incredibly scarce and I’m surprised at the values, my first one was a cased Scharffenburg and I bought it from Detlev for $800 usd. I agonized for weeks over it but it was just too special to pass up. I’ve surfed the web for awhile now and the only one who seems to have had a steady supply is eMedals but many of the pieces Barry has sold are not ones I’d want in my collection. I’m visiting a fellow collector in October, he has a gold ca. 1870 RK that I’m hoping to see again. It’s so beautiful and different with the fixed crown. Looking forward to that trip!
