GHD5 was used from late 69 to late 79, the final G denoting Abingdon build was used from 1967, so is correct. PaulH. ----- Original Message ----- My paperwork says GHDS (S should be 5) UA 1933394G. So I have the required six digits - I see that following models used "G" as a 'made in Abingdon' indicator - so maybe someone got premature??
