Took me a while to find that, 'just before' being 3 years ago. I was referring to manufacturing in general, Shipbuilding, trains, televisions etc, as I explained after the para you quote.
To a certain extent, car manufacture has bucked that trend. In the 70s most of the cars were bought here and few were exported. Now we have the opposite, and most go for export.
