Walker’s name makes a brief appearance in the history of letter boxes when he took over the Eagle Foundry in Birmingham from Smith and Hawkes. His name as BERND P WALKER is found on large size wall boxes cast from 1874-1879. It also appears on medium size and small size wall boxes. In 1879 the name was changed to B P WALKER on all three sizes of wall box—but as they were made for just a single year are very scarce.
