Aircraft Part LY 1678 Knob New Qty 4

This item was purchased from an aviation surplus sale. I do not know the history of it. This was a large parts bag of several of these same items that I am splitting up. The package was tagged, "Condition: NE".  It is not tagged as to the aircraft type. It only comes with what is shown in the pictures. I have more than one of these and so the one you receive may not exactly match the pictures, but it will be new in the package.
