The LGOC B-type is a model of double-decker bus that was introduced in London in 1910. It was both built and operated by the London General Omnibus Company (LGOC).

Associated Equipment Company (AEC) was a British vehicle manufacturer that built buses, motorcoaches and trucks from 1912 until 1979. The name Associated Equipment Company was hardly ever used; instead, it traded under the AEC and ACLO brands. During World War One, AEC was the most prolific British lorry manufacturer, after building London's buses before the war.
