I found a small stash of these in Japan and brought back a few pair, in two different versions. Boxes for both versions have shield logos and are labelled: "SYNT (r) Pattini Sinterizzati." Packaged 4 to a box. My sense is they are either at the very end or slightly beyond the CR timeline.
The ones pictured in the ebay auction have red side panels on the box, oval ends, two horizontal channels in the face of the shoe (parallel to the long edge), and a shallow channel on the rear face (parallel to the long edge). I was told these were for Delta brakes.
The second version comes in a box with purple side panels, has flat ends, no channels in the shoe face, and a large/deep channel on the rear face (perpendicular to the long edge). I was told these were for "Super Record," but they look identical in shape to early Chorus monoplaner caliper shoes. The channel/cut-out on the rear clears the head of the shoe-mounting bolt, which protrudes further into the shoe holder on Chorus than on the classic Record ones I've seen. Note that I haven't dissected enough last-gen Record/"Super Record" shoes/holders to know whether there might have been a running change to the Chorus-type shoe holders.
My apologies if these are out of timeline.
Cheers,
