I believe that Super Record rear derailleurs with no date stamp were from the last run of them, perhaps about 1985 to 1987. Same goes for Nuovo Record. Others on the CR list will likely know with more certainty.

... remind me of what it means if there is NO DATE on a Super Record derailleur? Did they ALL have dates or did some brandish dates while others didn't, concurrently? I scanned the archives but didn't find an explanation.
