Hello, sounds like the plate mark of Ad. Frenais from Paris. The 12 is the amount of silver in Gramm applied during electroplating. The mark is most likely in a square, isn't it ? The "Blang" is actually "Blanc" for "Metal blanc", the base metal, which in this case is not brass, but German Silver, an alloy of copper and nickel among others. Best wishes, Bahner
