THE armoured car Lenin stood on to address demonstrators at the start of the Russian Revolution will take pride of place among the largest ever gathering of Longbridge built vehicles. Its the only known surviving example of a 15hp Austin armoured car and is presently in the Military Vehicle Museum in St Petersburg. Digby Jones, director general of the CBI, secured it for the 100th anniversary of the Austin Motor Co and continuous production at Longbridge with a letter to the British Ambassador in Moscow. The ambassador contacted the British Consul in St Petersburg who managed to get the go-ahead from the museum's directors. The event, on the weekend of July 8 to 10 next year, will see thousands of examples of Longbridge-built vehicles of every type gather at Cofton Park opposite the factory. It is being billed as a once in a lifetime opportunity to see as many products from the Longbridge factory as are ever likely to be assembled together in one place. The armoured car was one of several hundred ordered by the Tsarist Government between 1914 and 1916 but is the only one still surviving and the link with Lenin makes it unique. The birthday celebrations are being organised by the Federation of Austin Clubs, Registers and Associations and are supported by Phoenix Venture Holdings, the owners of MG Rover. Birmingham City Council has approved a parade from the city centre to Cofton Park. At the park there will be everything from stately Sheerline limousines to diminutive Austin Sevens and Minis, taxicabs, military vehicles, Devons, Cambridges, 1100s, 1800s, Maxis, Allegros, Montegos, sporty Austin Healeys and Princesses.
