rudder question, what is my rudder from?

[Cavi]

Last year I bought a complete rudder assembly off E-bay for my sunfish. All the hardware is correct and it works fine but it is longer, it is like 38 inches long instead of the 25 inches it should be. It seems to work fine, but I am curious as to what it might be from.

Post a photo. If it works it might be a Force 5, Puffer or Zuma rudder. They had longer blades and beefier rudder cheeks.
