Wheelers are difficult to identify as there's loads of different models. However it is a 94/95 model as it has the same cable routing with the noodle tube for the rear canti as my 8800 ti team. The decals should be wheeler on the down tube with the model no. on the seat tube. The paint looks original, so is it not possible to see the subtle changes that usually occur where decals have been ?. Failing that you could try one the German forums i.e. mtb-news.de as they are a well known brand in Europe.
