Help Me Identity My Pool Pump

[structre40]

Can anyone identify my pool pump? The motor is Magnetek but I can't for the life of me find the actual pump manufacturer. I scoured the internet for the shell logo which is about all I can make out from the pictures.
The closest looking pump I can find is the Pentair Challenger based on the clamp and design. I need to replace the shaft seal on it and want to make sure I get the right part.

Thats like my old pool pump at our old house, it is a Pentair Challenger, the motors were typically Century or Magnatek branded.

Thanks a bunch. I believe that confirms what I found on Google image search. Thanks again!
