The image in the profile N92975 is not a Commonwealth 185 Skyranger.
The Skyranger is a 2 seat high wing cabin monoplane, not the single seat biplane pictured. I cannot identify the aircraft in the photo.
I have checked the FAA Registry, and N92975 is currently unassigned, but was previously issued to a Skyranger which has now expired.
Sorry Dariusz.
