I remember seeing a very old post on here where someone was riding around an extremely tall Schwinn that looked very much like that, and then I could never find the post again.
Stuff I see that makes me go hmmmm...
The stem and bars. The joint where the lower bar attaches to the seat tube. The seatpost bolt location. The fenders with the screws so close together, and not only that, they are screws. The fork crown.
Is this thing really a Schwinn? Hopefully some CABErs with actual knowledge will comment.
