That is most decidedly a legitimate Greenock board, no question.
All Greenock boards use a generic label (of varying types) but can be identified by two black or blue marker or pen initials on the label in the vicinity of a 'QA' and 'AI' or 'I'. Those are the QC marks - Quality Assurance, Assembly Inspector and Inspector respectively. The Danish/Icelandic 102 was manufactured until at least '99 due to not having a suitable replacement available for Icelandic. The substitute dome version (71G4621) was only Danish-QWERTY.
