66 Chevy Radio Identification

[paulspickupparts]

I recently purchased a bunch of parts from a large group of parts from a retiring truck enthusiast that had mainly 64-66 Chevy Pickups . I have never seen a radio like this , just wondering if anyone else has or any information on it. The dial bezel looks similiar to the 60-66 Chevy Pickups but of course different letters and then of course the push buttons . Appreciate any information or input. Thanks
