AEC NS type 405 to 410 series Bus
The AEC 405 type, perhaps better known as the NS, first made its appearance in 1923, although construction had begun during the autumn of the previous year. Having a wheelbase of 1Sft 6in, it was 25ft length and 7ft 31/2in width. Fitted with an AEC 4-cylinder 35hp petrol engine, it had a multi disc clutch running in oil, a 4-speed constant mesh helical gearbox and double reduction rear axle.
The NS type was fitted with solid tyres, although later in their lives, many were converted to pneumatics. Models 405-408 were produced exclusively for London General Omnibus Co and its associates, and it was not until 1925 when the 409 model was introduced that it became available to other operators.
Production ended in 1927 upon the arrival of the advanced NS model, classified the 422, with over 2,000 of the 405-410 models having been built.
