W with G or stylised C O to make Co ? The other side is even more frustrating as the letters are almost legible, can anymore be made out on the original please Rob?

From Rob - "Im 95% certain it says Muhler Berthier-Hamburg."

From Paul Cannon, "I think I can read MÜHLENBETRIEB ie mill operation/works, with the name of the town below probably MARBURG. The other face W 00, grade of flour."
