Lot of Gyro Caging Knob Mechanisms (External) for Gyro Horizon Indicator C-5 C-7 AN-5736
Here are 6 spare Gyro Caging Knob Mechanisms for the Artificial Gyro Horizon. Without a part number, we can't state if these were used in both US WWII-types C-5 or C-7/AN-5736. Note that this is just the external mechanism for knob caging and does not include the knob itself, screws, or internal gyro-caging mechanism.
Price is for all 6 shown in the photo gallery.
