Notice the vacant land to the northwest of the "H" in Hewell Road. There is where the cafeteria was later to be built. The cafeteria is still there today, as can be seen in this 1999 picture,
Most of the factory is gone, as we know, but the picture allows to quickly see what is left, in particular the iconic building that says "Royal Enfield" on the roof. However, a new discovery is that the building has four bodies that were part of the original factory. I hadn't been able to determine that, even by being there on the ground, since the two bodies to the right sit behind a fence today.
