I’ve searched all over google, AAPK and BF and can’t seem to find much info on these knives. They aren’t listed in the old Queen catalogs. I read that SMKW had Queen make them for some kind of live show they used to have. I don’t know if there’s any truth to that. I love these knives and the quality is excellent! I wish I knew more about them though. I’ve done my best to complete the set. I have a stag on the way that’s not pictured. Other than that, I think I’m only missing the blue jigged bone and the Crown Jewel in the 48 pattern. I could be wrong though. If you have any info, please share it!
