This item was found while organizing the warehouse. I am not knowledgeable about this item, so I cannot answer specialized questions. I do not have batteries on hand, so I have not been able to confirm its operation. The three knobs on the left side are missing, and the pop-up antenna functions normally. Would this be suitable as a restoration base or for parts? It is a used item that has been stored for a long time. No claims and no returns are accepted.
