Thank you for your comment, and my apologies for overlooking your question. The Jan Knedler VM’s are one of my favorite of the privately made issues. The maker’s mark is “I K”, which is consistent on all Knedler silver crosses and badges that I have seen. I have no idea why the “I” is not a “J”, which would of course make more sense.
It is a thick and heavy cross. Attractive design elements such as the distinctive eagle (copied by Panasiuk), split wreath and the larger ball ends coupled with Knedler’s reputation for exceptional quality all result in a winning combination.
