This is the engine bay of TF HDA46/7249 which is a very well preserved 21,000 mile example. Note the engine red paint on the front of the dynamo and the tension slide. It appears that a cover was slid over the barrel of the dynamo before the whole unit was painted red. The dynamo pulley wheel was also red as these were made by Morris, not supplied by Lucas. The rocker cover may also have its original paint.
