St. George Chess Set with Stamped Box: "Leuchars 3 Cheapside"

Jon's main chess page
A nice Victorian St. George set, but the unusual feature is that this set came in its original box with a label (barely legible) that includes "LEUCHARS" and "3 CHEAPSIDE". Further research in the London Directories shows that Leuchars had a toy warehouse at 3 Cheapside, starting in the mid 1850's, in addition to his normal location at 38 Piccadilly.
