Alvis TD21 Convertible manual ZF 5 speed transmission 1961

Differentiating between the Alvis TA 21, TD 21, TF 21, and TE 21 can be challenging as they belong to the same series of Alvis models and share similar styling cues. However, there are a few key distinguishing factors:

Badge and Model Name:
The models can be identified by their badges and model names. The TA 21 typically carries the "TA 21" badge on the grille or rear of the car. The subsequent models, TD 21, TF 21, and TE 21, would have corresponding badges indicating their model names.
Grille Design:
The grille design can provide a clue to identify the different models. The TA 21 usually features a simpler and narrower grille compared to the later models. The TD 21, TF 21, and TE 21 have a wider and more prominent grille with additional chrome detailing.
Bumper Configuration:
The bumper configuration can vary between the models. The TA 21 often has a single-piece bumper, while the later models like the TD 21, TF 21, and TE 21 feature larger and more pronounced bumpers with additional overriders.
Rear Design:
The rear design of the cars can also help in distinguishing between the models. The TA 21 typically has a more rounded rear end with smaller tail lights. The later models, such as the TD 21, TF 21, and TE 21, have a squarer rear design with larger and more elaborate tail lights.
Interior Features:
Examining the interior features can provide further clues. The later models, like the TD 21, TF 21, and TE 21, often offer more luxurious and modern interior appointments, including upgraded materials, additional instruments, and improved comfort features.
It's important to note that these distinguishing factors are general guidelines, and there can be variations and specific details within each model. If you are looking to identify a specific Alvis model accurately, it is recommended to consult an Alvis expert or refer to official documentation and records associated with the vehicle
