Metal mechanical lobster sculpture

All movable parts metal mechanical lobster sculpture. It about 7" in length (body), overall about 20". I tried to find the artist but no luck on the internet. Comparable artist range from $100 to $500, non movable parts. This is a well made piece, all parts are functional with detail on the body. The artist name is on the sculpture on a sticker, you can tell its the orginal. Asking $250. If you can local artist, please let me know and we can negotiate price.
