Indicator question 1994 GP

Afternoon all...just got my recently acquired 1994 M Reg GP MOT`d. The tester was not going to MOT it as he stated that it should be fitted with indicators (anything made after 1986 should have them, apparently) . After a discussion he agreed to MOT it as he thought it was probably imported to the UK in 1994 but was probably manufactured many years earlier. When I got home I checked my V5 which said it was declared new when imported (1994) so I guess legally it should have indicators fitted even if it`s retrospectively ?? Funny thing is, I`ve got the last ten years` MOT certificates so it doesn`t appear to have been a problem up until now. Anyone have any experience of this, any loopholes etc. Not sure what to do about next year other than going to another MOT Station and pleading ignorance.
