A total of 602 vehicles[1] were manufactured between 1933 and 1940, with model codes running from TA to TF, TJ and TK.
Common to all vehicles and advanced for the time is the use of a front independent wheel suspension with a semi-elliptical transverse leaf spring, which Alvis introduced in parallel in 1933 for the Crested Eagle and Speed 20 SB models.
Special bodies from at least eleven different coachbuilders are known, including four-seater tourers from REAL (R. E. Alltman Ltd.), two-door convertibles from Vanden Plas, Cross & Ellis, Carlton and Charlesworth, and other one-offs from Martin & King, Samuel Holbrook Ltd., Salmons and Son and Mayfair.
[1] The Alvis Crested Eagle was available in various versions, which differ primarily in their year of origin, the engine variant and the wheelbase.
As a chauffeur limousine or as a 6-light saloon with a total of six side windows and a wheelbase of well over three meters, certain of the model series have been considered 'upper' or even 'luxury' class.
