Puzzle maker is Charles Russell, Auburn, MA, a man I got to know in the 1970's when I commissioned him to cut over 40 puzzles for us (but not this one). This is a typical Russell puzzle: interlocking, cut along color lines with interval knobs and trick edge pieces in a round knob style, and 21 figure pieces. Saltwater Cove is a series of Westcott Bay Novels by Amelia Adler. and the ponds made by the ocean along low level shores. A previous owner arranged for a puzzle maker in England to replace 2 pieces, one of which I replaced as it wasn't very good. There is a note in the box describing the process. Picture may be photo.
