The only aircraft in which the Siddeley Tiger flew was the ill-fated prototype of the twin-engined Siddeley-Deasy Siniai of which three were planned to be produced.
The Siniai was powered by two 500 hp Siddeley Tiger water cooled engines, a new V-12 design produced by combining two straight-6 Siddeley Pumas onto a single crankshaft.

The Siniai was the third and last aircraft design produced by the team led by John Lloyd and F.M.Green at Siddeley-Deasy before they were rebadged by merger as the Sir W.G.Armstrong Aircraft Company.

One thing that did surface was that Hawker Siddeley and Tracked Hovercraft were in the process of entering a bid for the GO-Urban system in Toronto.
Further diversification occurred in 1901 with the acquisition of a proposed business which was incorporated as The Wolseley Tool and Motor Car Company and in 1905 the goodwill and patent rights of the Siddeley car.
The Rootes Group, by then owned by Chrysler Europe, purchased the 187 acre site from Hawker Siddeley Dynamics in 1969 for the purpose of centralising all its design and engineering teams onto one site.
