Personally aside from the brifters I think most of the 105 is older like '88ish. The 105 was 105SC with that creamy champagne finish, much shallower crank spyder and dual pivot brakes.
I don't think Torelli had model names for their bikes just frames. The sold frames and I think Sachs kits I don't recall them selling shimano. Their big claim to fame was you could get into a nice riding SL framed Italian bike for about 30% less than a DeRosa or Merckxx.
I kind of like the colors but I think may be a bad home spun respray or partial to get a two tone effect
