How can I tell if pre-flag Master chalk is the real deal?

John,

Who are the major chalk manufacturers? We know Tweeten makes Master, Triangle, and Blue Diamond. I have a box of Brunswick chalk, and was told its really Masters. Does Tweeten also make Silver Cup? If so, its a great marketing idea to drive customers to the Master brand.

As someone who has purchased nearly a million cubes of Master chalk from Tweeten I have kind of an insight on the chalk thing pre and post flag.

But admittedly, some have taken the study of chalk to much deeper levels.
