I picked up a bronze buckle from one of our great vendors. I did a forced patina on my Benarus bronze watch, Benarus bronze buckle, and third-party buckle. The third-party buckle is a completely different finish. The vendor never represented that it was the same, just that is was phosphor bronze. Benarus clearly states they use CuSn8, so the third party buckle must be a different bronze. Anyone know where to get one that is definitely CuSn8?
