I know of gun parts being made from latex molds. They make the latex mold them cast a wax part. They coat this in ceramic and burn off the wax. Then pack the ceramic in casting sand and cast the part. Not sure what material you want to cast but it would seem like with all the folds of skin and the wattles it would be a challenge. Would plaster of Paris work for a mold to cast using some bait plastics?
