Memorabilia
Brass checks (tallies) swapped for a lamp at the lamp room told the banksman who was underground. Plates and checks tie a lamp to a pit. Bridles, brasses and non-sparking beryllium-copper shoes come from the ponies that hauled underground until 1994 in England. Enamel signs, mine telephones, changehouse baskets, union banners and badges belong here too.
