These were recently contributed anonymously.  I was contacted a few years ago by another collector who sent photos of these and more from his collection, but I was not able to post them in a timely manner at the time and shortly after lost the files and contact info due to a hard drive crash. I finally recovered those files and have posted photos of the exteriors of the cases above and the two knives below. If you see this page, please contact me and allow me to add additional examples from your collection to the page and credit you properly!
