I currently have 2 sizes of quadrant hinges suitable for small boxes available on ebay. These are high quality very classy items. I sold some at the recent TTG sale in Sydney. The smaller hinges appear to be more of a bronze rather than brass and have a very nice 'gold' finish which you can see in the photos.
