It is a Weir W-6. A Scottish Company.
With the assistance of Juan de la Cierva, the Weir Company had formed an aircraft department in Scotland in 1932. The W-5 was the Weir Company's first true helicopter design. Initially, the W-5 was a coaxial design, but concerns about stability and control as well as the success of the Fa-61 led to the redevelopment as a lateral side-by-side configuration, which flew successfully in June 1938. Control was achieved with cyclic pitch but there was no collective pitch; vertical control was obtained by altering the rotor speed, a cumbersome feature used also on the Fa-61. The W-5 reached speeds of 70 mph in forward flight. The Weir W-5 (and later the W-6) and the Fa-61 were technically ahead of Sikorsky's VS-300 in terms of flight capability, but the VS-300 was ultimately to set the new standard for helicopter design. The Weir W-6, which first flew in 1939, was a much larger version of the W-5 but still used the lateral side-by-side rotor configuration. Further work on the Weir designs was suspended at the outbreak of World War 2.
