There was very few changes on the Triumph TR3 throught production period. But one detail helps to sort a TR3 among TR3 As or Bs : the front grille. While early TR3 had a small air intake (shaped like TR2's) with a thick square pattern grille, later Triumph TR3 A and B have an enlarged grille where parking lamps are fitted.

Triumph TR3

Triumph TR3A and TR3B

Do not trust the hood and screens, they do not  prevent from water leaking inside the car when driven under pouring rain. So what ?	Anyway, the TR3 is more funny to drive top down, under the sun.	This TR3 is fitted with steel wheels.	The tank filler, behind the tonneau, is common to all Triumph TRs and Spitfires. For your own sake, never ever overfill.
Strangely, this TR3 est fitted with a TR4 steering wheel. Perhaps original on late TR3B ?	Behind front seats, a so called rear seat could be added.	A very nice wheel center finisher on a TR3 steel wheel.	The Triumph "TR3" badge, as seen over the grille. .
On the TR3 A and B, the chromed "TRIUMPH" letters are added below the front badge.	The red trim contrasts with the black body's colour.	This one is red with a black trim.	A tonneau cover protects the car's interior from the rain and burning sun..
This is a mandatory equipment.	Cars exported to France were equipped with yellow tinted lamps.	The TR3's boot is very small, but a luggage rack can be added.	The hood is attached with ten fasteners to the windscreen. Look accurately and guess were the rain goes.
