Howdy! I lovingly restore the good 'ol mechanicals and I have a very nice gently used 1392366 with box. Rivets are in great shape and aside from a small cosmetic issue here and there, it's about as good as you can find outside of being new. I thought I'd ask here first before the keyboard enthusiast forums. I know it's a rather elusive keyboard so if it could be paired up again with an RT I'd be thrilled. Kind regards, -Maxx
