First, I do not have your answer, only some more fill in information.
I have seen that head badge. The Schwinn Planes/Trains/Automobiles. It was on an "old bicycle" that I owned more than 60 years ago. The bicycle was old when I bought it. It was a 24" wheel boys brown and creme "post war" Schwinn balloon tire. I remember the name plate graphics and Schwinn, but I do not remember it saying Delcraft? Maybe it did, maybe not? It was an original Schwinn name plate, on a Schwinn bicycle, and it had the Planes/Trains/Automobiles artwork. It was very cool.
You might ask why the hell would this old man remember that one bike? Out of all the bicycles I have owned, raced, ridden, sold, etc. I had my biggest crash ever on a bicycle on that bike. Let's just call it memorable. I was a kid racing around the empty grade school sidewalks during summer vacation. I turned a corner, flew off the bike and did a face plant into decomposed granite walkway. I was plucking granite bits from my chin for a long time after that excursion.
