What brand, model, and year of bikes came with a Shimano 105 6-speed group set? I think that would be Shimano's "1050" group set (i.e., indexed downtube shifters, BioPace chain rings, toe clips, etc.)

I'm the most interested in Trek models as they are the most readily available near me, but any brand or model available in the USA is fair game. I've taken up restoring bikes as a hobby and am finding that 105 isn't a much sought-after group set but is still of reasonable quality, making bikes equipped with it somewhat affordable on the used market. The hard part is weeding-out all the used bikes that aren't 105 equipped.
