91-95 Kit. I didn't show it as 1mm over, but I have it in my 93, 94 and 95 Kit manuals. I don't see it in my 92 manual by part number but it is referenced, so I assume the same.
Likely you are right Scott. I was looking through old fiche and it is a number that supersedes another number (#13001-1374). As I connected numbers, it appeared to be a 1mm O/S piston but I could be wrong. Your info from the race manual is likely the most accurate.
