Maybe later 710s has this fork crown, I'd just never seen them without the Haden.
Some 610s had 531 fork blades too (still assembled in Japan).
But I think I've seen 610s where the head tube isn't painted like it is in the catalog (to match the seat tube panel).
Serial number does tell all here. '82 614.
