Alvis had previously contracted AP Metalcraft, a Coventry coachbuilder, to produce the TB 14 two door open car body to fit on the TA 14 chassis. With the replacement of the TA 14 by the larger TA 21 in 1950, AP were asked to modify their design for the new running gear. The TB 21 dropped the controversial grille used on the TB 14 in favour of the traditional Alvis one. The doors, rear hinged, were heavily cut away at the top and the windscreen could be folded flat. The 2993 cc engine was slightly modified to produce {{convert|90|bhp|abbr=on}}[1] with a single SU carburettor replacing the Solex one used on the saloon. The TA 21 suspension was retained, independent at the front using coil springs with leaf springs at the rear. As the car was lighter than the TA 21 the final drive ratio was changed from 4.09:1 to 3.77:1 helping to increase the top speed and improving economy.[2] The car could reach {{convert|95|mph|km/h|abbr=on}}[2] but was very expensive at £1598[2] on the home market resulting in limited sales.
