The workmanship is good, with a thick build and distinct unevenness around the teeth, and the G-crown on the forehead is also firmly stamped. It weighs 51.9g, while the larger sizes of the pre-owned and Maria rings usually weigh around 42g, but this one is quite heavy even at size 17. I've taken a comparison photo of the profile with my current jawless ring and keychain, and I think you can see the angle of the forehead, which is characteristic of the pre-owned pieces. Because of this different forehead angle, the engravings on the current large skull rings are often not very good. I've also included new images comparing the current size 17 jawless ring and this pre-owned jawed size 17 ring; the fit is the same, so I've added new images. The back side clearly shows that the pre-owned ring is thicker. I own a pre-owned flat-back skull, so I hope you can use it as a reference for the G-crown on the back. This ring is from an even earlier period than the pre-owned pieces from around 1995 that are often seen in Japan, and it's likely from the early days of the large skull ring when the motif hadn't been finalized. According to information I received from the buyer, it was purchased at Bill Wall Leather in Ueno, Tokyo. The January 2017 issue of SENSE magazine features a Bill Wall Leather special, and it includes a large skull ring that is almost identical in mold to this one, presented as a work by pre-owned Gabor Nagy. I've included images for reference. Normally, the right cheekbone area bulges out, but this ring and the one in the magazine are slightly concave. The eyes of the usual large skull ring are pointed on the upper left and right sides, but those of this ring and the one in the magazine are more subdued. Furthermore, what's particularly noteworthy is that this large skull ring has vertical lines on the jaw area. You can't create them; you can only remove them. I can surmise that it is older than the one in the magazine. As such, I believe this large skull ring is a piece that Nagy himself gave to Bill during the collaboration between Nagy and Bill Wall Leather during the pre-owned era. I will give this SENSE magazine to the buyer, so please take a close look at it. There are also other pre-owned Gabor pieces that haven't been released. Before Nagy built his atelier, Bill, as a business partner, made the main leather goods, and Nagy made the silver decorations for them. I believe this is a genuine pre-owned Nagy piece that Bill owned, so I'm looking for someone who will cherish it. This is a high-value item. I do not accept returns or cancellations after purchase, so please ask any questions beforehand.
