Received my replica...3 trips to post office later playing tag with delivery person. Haha. I did a simple wash of acrylics black and browns. Had to file down one spot but once it starts to naturally weather that will vanish. Thanks again.
Cutting out a 10x10 wooden square out of 3/4" wood. Beveled edge painting whole thing black and adding some type of silver 9x9 sheet or plexi cover for background. As for mounting using pegs to hold cane and rail to hold brooch.
