Question about Nordost Power Cables

I have purchased used Nordost Shiva and Vishnu power cables here on the 'gon. One thing that stands out is the fact that none of them have the Nordost heat shrink jacket at the termination. Can anyone tell me if these are factory cables or if they have been re-terminated?
There could be a third possibility..they are fake Nordost. Take a detailed picture and send it to Nordost or take them to an authorized dealer for verification.
