Team Weinmann 1991 "camo" (and I see it - "pink bottom") could not appear until late autumn 1990 - the trouble is that the designation of your frame is 1989 ... someone in EMC was clairvoyant or the frame was repainted ; you can not see any model / tube markings - for TSX it should be TT, for SLX - X. There is one more option: someone instead of C chose B (I saw at least once the frame marked in such a wrong way). Show more pictures, it is rather over-painting (perhaps at EMC factory - they did this often to the order of customers who wanted to "upgrade camo".
