So what I think maybe some are not putting together here since it’s been called planes trains badge for like forever , is that this is theeee true Schwinn badge... schwinn is the name in big letters across the front. Just like excelsior or Lasalle or ace or liberty or whatever As to why it sometimes has the matching schwinn dt decal. But to answer why some do and don’t... haven’t a clue. I have only seen schwinn on the PT Schwinn badged bikes and like Bob said, some have it some don’t.. I think certain badges got decals and others never did. Seems like a lot of the chicyco and Louisville bikes had them.. Lincoln, Lasalle, liberty and whatever the Louisville bike one was....... what did schwinn have? Schwinn, excelsior, paramount, the world, majestic and ace? and autocycle for decals? . now that I think about it, those seem to be the only true schwinn ones no? I know when we get to snap tanks there is also a motorbike tank decal. But I can’t remember if there is aDT decal on that. Think it said schwinn? So basically all the old schwinn big names get decals, the motorcycle brands they bought and had made frames for. Then the world which was like their first real branded thing right? And then the paramount line...
