King Aircraft Angle Assembly KA350

These units were purchased from an aviation surplus sale. I do not know the history of them. They are in good cosmetic condition. They are tagged, "Part Number N/A, Acft. Model KA-350, Reason for removal, MOD". There are two pieces here. One is marked, "RH Top", the other is marked, "LH Top". They measure about 13 3/4" long x 1" wide. I am not able to test them. It only comes with what is shown in the pictures.
