I dare say there was no interest in the 80s for a HW85T. Weihrauch struggled to sell the 85 back then and a T model would have been about £80 more than the base model if production of the 80T and 77T are anything to go by. It seems once the 80 and 77 were introduced a light weight alternative wasn't the answer for some reason. How times have changed!. Mach 1.5
