Hey giffy,
I think that the UFO''s were designed by Holman & Pye in the UK - I know that they did the UFO 34''s - but I''m not entirely sure about the 27.
They may well be able to point you in the right direction. If memory serves the UFO''s were one of the 1st breeds of genuine "Cruiser/Racers".
Cheers
