Antique store Turks Head Copper Hammered Mold

A very unusual hand hammered copper Turks Head mold. Measures 10 ¼ inches wide and is 6 inches deep. Tin lining which is in excellent shape, could have been re-tined ?? Copper triangular hanger. Top has an Indentation where all the swirls meet. Rolled rim edge. There are two marking A symbol trident. and a backwards L., pictured. I have tried to figure out who's mark this belongs to with store no luck. I t could be the owners mark. I can find another one like this on the Internet. Gorgeous piece.
