Are you referring to the advertisement? What is actually in the ad? Golden Arrow or 105 components? I know that bike catalogs in 1987 referred to the 105 group as the "new shimano group". Unless those are Golden Arrow (and not 105) components in the ad, I'm not conceding that because the ad has a Golden Arrow logo in the ad, that that means that Golden Arrow was known as 105, prior to "105" being introduced as a group.
