Alexander Mollison was first in partnership with James Emslie, as Emslie & Mollison, c.1835-1837, and then in partnership with James Begg, as Begg & Mollison, c.1841-1844. I dare say your pieces could have been made before, in between, or after these partnerships, but following the passing of the Plate (Scotland) Act in 1836, Scottish provincial marking went into decline, so it likey that your ladle and tongs are earlier, rather than later.
