So Hause you think just a poorly stamped HB? The Birmingham proofmaster had quite a wide girth, as did most proofmasters, so I'm confident that the Liege makers had the Liege proof facility to send their wares in the white to the Birmingham proof facility & from there I'm sure Clabrough, etc. had a relationship w/ the proof facility to acquire the price point platforms.

Cheers,
