What I recall from the 86-87 Championship sticker is that bikes could be as late as '89 with those. It's sure not an '86 (I checked the catalog). Definitely between those years.
Something Bianchi Girl keeps reminding me of also is that not everything is consistent with these bikes. Maybe your top tube decal got replaced by an owner or at the factory, and was supposed to be block lettering?
