These are the stock Cessna Control Wheels removed from my 1973 177RG, SN 177RG0349. Reference: 177RG Parts Manual, Figure 69, Index 54A, Part Numbers 1767078--2 (without Mike Switch), and 1767078--3 (with Mike Switch). They are in good shape. The Copilots yoke is (factory) drilled for a PTT, and the Pilots yoke is not drilled. Comes with both collars, Re: Figure 69, Index 56, Part Number 156319-2. $380 and I'll pay shipping costs to the CONUS.
