This is obviously not a stock locker. I know what a gov-loc looks like. I had to cut one in half to remove it after it locked up. I'm about 99% sure this is a Detroit, but all the pictures I can find have a different looking case. I'm sure they are just a "stock photo" for Detroits, but I just wanted to be 100% sure thats what this is. It has a "D" in the casting as you can see in the picture, and it does take a larger inside diameter carrier bearing than stock carriers.
