Fire Insurance Plaques on Buildings Told Private Fire Brigades Whose House They Were Expected to Save｜房子外牆的金屬牌，曾直接告訴私人消防隊這棟樓歸哪家保險公司
WHAT 這是什麼
London Museum explains that fire insurance marks were placed outside insured buildings to identify the insurer. Before standardized street numbering they helped identify properties, and insured homeowners expected the relevant company's fire brigade to respond.
WHY HERE 為什麼屬於底域的世界
服務關係被釘在建築外牆上；一塊小金屬牌同時把地址辨識、金錢契約與救火行動接到城市空間。
BLIND SPOT 補了哪一塊少看的視角
這是特定時期倫敦私人消防與保險史；不能把它簡化成『沒有牌就一定不救火』的單一規則，實際運作更複雜。
