I was finally able to frame the uncut sheet above. I have been looking for this sheet for quite a long time, it is deceptively hard to find despite being 92MM and a common set. Major thanks to a fellow board member who gave me a lead on it, putting me in touch with owner who was selling (and who was very friendly and nice to work a deal with).
Probably my fav insert set of all time (and no this is not the 92MM Platinum…it’s the OG)
