Well my friend, first Anonimo use Bronze so is not brass.
I saw a run of 29 pieces that means is 30 pieces... 00 to 29... But Polluce Bronze with a OxPro bezel... Better if you can post pictures because bezel is Stainless Steel with a OxPro finish so the result is a darker close to black color finish.
Really want to see your timepiece to help better.
