I can add that the Hamburg city mark with the letter "T" was the mark of assayer A. F. Lammatsch, who served from 1811 to 1828. Laué's death is not recorded, but he either died or retired by 1824, when his seat in the Hamburg guild was succeeded by J. J. Groth. So your sugar box dates sometime between 1811 and 1824.
