of rolling stock over the years, culminating in the construction of four large 2-8-2 tender engines in 1928. Six very powerful superheated 4-8-0 mixed traffic locomotives built in 1929 were the last of a series of 4-4-0 and 4-6-0 machines built for the Buenos Aires Central Railway of Argentina. In common with most British locomotive builders, in the postwar era Kerr, Stuart received a number of large orders from the mainline companies who were seeking to replace obsolete inherited equipment with their own standard designs. In 1920 the Metropolitan Railway ordered eight superheated 4-4-4 passenger tank engines for the Aylesbury service. Between 1925 and 1927 the Stoke works built fifty standard class 4F 0-6-0 goods engines for the London Midland and Scottish Railway and in 1929 and 1930 a batch of 25 GWR 5700 Class 0-6-0PTs were built for the Great Western Railway. Diesel locomotives In the late 1920s a number of diesel locomotives were built. These were available with two or three axles for various track gauges. The engines were by McLaren-Benz in 2-cylinder (30 hp), 4-cylinder (60 hp) or 6-cylinder (90 hp) form. Transmission was mechanical and final drive was by roller chains. They were very successful even though technology moved on quickly. Further development was stopped when Kerr, Stuart's went into receivership, but the Hunslet range of diesel locomotives was based on these. At least 3 Kerr, Stuart diesel locomotives have survived into preservation but none is in original condition having been given different engines. The company in liquidation On 17 April 1930 a petition calling for the company to be wound up compulsorily was presented in the High Court (Chancery Division) by the Midland Bank. At a hearing held on 8 May 1930 this petition was withdrawn on settlement of an £8,000 guarantee. However, the sale of the works to George Cohen, Sons & Co Ltd was announced in August 1930; a skeleton staff was employed to complete contracts in progress. Another winding-up petition was presented on 10 September 1930 and an order was made on 14 October. At the creditors' meeting held on 14 November Herbert Langham Reed, the company's chairman and managing director, attributed the failure of the company to the locking up of capital in the Peninsular Locomotive Company, registered in India 1921 to build locomotives (Kerr, Stuart held 80% of the capital and loaned £78,000), the [April] winding-up petition, which had resulted
