Model (scale 1:6). Demonstration model of a fire escape made by Abraham Wivell to illustrate a series of lectures on fire-fighting that he gave in 1836. This particular extending ladder was les popular than the model incorporating a canvas rescue chute, and both were superseded by the lattice-girder extending fire escape, patented by James Shand in 1880. Wivell was responsible for 85 fire escape stations being established in the London district.
