All,
Picked up a used setup that included a skimmer that I'm not too familiar with. It looks like a Precision Marine, possibly an old model or something. The pump that came with it is a Little Giant, one of the largest models...4 something or other.

I have included a pic of the skimmer for reference. Any info would be greatly appreciated.

I have a few more pics at different angles if needed.

Also, there is another hole inside the body of it that is threaded. Is anything else needed to make this skimmer work correctly.
