Model (scale 1:6). One of the types of horse-drawn omnibus used in London in 1855. The so-called 'Knifeboard' is the low longitudinal roof seat, which was introduced around 1851 to increase pasenger accommodation. The bus was drawn by two horses and carried 12 people inside and 15 outside the carriage compartment. Cushions were provided on all the seats and the omnibus travelled at between six and eight miles per hour. The first horse-drawn buses appeared in London in 1829, and continued to be a major part of the city's public transport system until 1912, when they were superseded by the new motorised omnibuses.
