Hello Everyone- I am looking to refurbish old and made duplicates on the pintle/gudgeon setup below, picture is from smallboatrestoration.blogspot.com: Pieces seem to be bronze, most have a natural seafoam green patina with some good fashioned iron rust from hardware for good measure. Two questions: -best method to prep old pieces to use as patterns? -how to finish old and new pieces to be either a shiny or mat bronze? I have a whole set to start with on one boat, second boat needs a whole set. One of my pieces below: Thanks!
