AEC NS-type

The AEC NS-type was a double-decker bus introduced in London in 1923, designed by AEC in cooperation with the London General Omnibus Company, which operated it. The letters came from the Latin Nulli Secundus, meaning second to none. A cranked chassis allowed a covered top, a lower floor and a single-step entrance, though the police licensed it only as an open-top bus until covered tops were allowed in 1925. About 2,400 were bought by LGOC and they ran until the end of 1937. Only two survive, NS 174 in original condition at the London Bus Museum and NS 1995 in the London Transport collection.
