Aircraft Part King Air KA-90 Box 50-364322-604

This item was purchased from an aviation surplus sale. I do not know the history of it. It is in good cosmetic condition. It is marked, "AR, N712DB, KA-90". It measures about 7 1/4" x 4 1/2" x 2 3/4" tall. I am not able to test it. It only comes with what is shown in the pictures.
