You have a lot of different things going on with this bike. 24" wheels with 36 spoke rims, 6 1/2" crank in place of a 5 1/2" crank on a 24" wheel frame. But the thing that has me wondering the most is what is going on with the lower head bearing? It looks like it has two lower cones on the fork stem? A 24" frame has a shorter head tube than a 26" frame and this requires a much different spring fork. The fork in the bike looks modified to fit the short head tube. Maybe it's the photo angle, but it looks like something is off. The Schwinn 24" beach cruisers of the 1980's used a mixture of parts, including a fork with longer legs.
Schwinn did make 20", 24", and 26" spring forks long before the 24"/16" modified fork was used on the Krates. 20" and 26" spring forks were commonly seen, but the 24" (before the krates) were rarely seen.
