Pump House Gang

Critical Past bills itself as "one of the world's largest royalty-free archival footage collections."

In the footage above, workers at the Anglo-Iranian Oil Company (formerly the Anglo-Persian Oil Company) man the pump house.

Not sure whether these workers are loosening or tightening their grip on this product. Not sure why they are not wearing safety gear either. If this footage was shot today, you can bet they would be wearing hard hats and gloves.
