There really is no front and back. Since the pumps were on an island, a customer could pull up to either side of the pump and receive gasoline. My T-176 did not have a nozzle holder and there were no holes where one would have been mounted. I purchased a T-177 that did have a nozzle holder like the one you show and it had the ears broken off; had them welded back, grinded down the welds, painted it and it looked good to me. You are missing one of the ears. Mine was mounted on the side opposite the long door. Some type of small sign was probably mounted where the two holes are located; probably not a "contains lead" sign because they typically have 4 screws holding them in place.
