You covered it very well. Helenarou, Yuki and JK Horological (pretty much identical to Clark, but much cheaper) offer sets too. Sometimes it pays to mix and match. Hands can also vary from batch to batch. Here was a comparison, some broken links to images unfortunately: https://rwg.cc/topic/179042-ultimate-rolex-mercedes-hands-comparison/ Here's my 5513 with a Clark handset and Helenarou dial.
