There are lots of offshore rigging knock offs (rope, shackles, etc) out there... Like wire rope, I wouldn't trust anything without seeing the spool it came off and the attached factory ID. If you have any doubts take it to your local Samson rope dealer, they may be able to confirm it.
The eye splice looks way too short for a class 2 line splice, they didn't taper the tail (bitter end) and left tape on... and the securing line should be stiched through the line, not sloppily whipped... Samson gives very clear, easy to follow directions for splicing, in order to maintain line strength, and it doesn't look like they followed them at all. Personally, I wouldn't trust that eye, and that would make me suspect of the lines pedigree.
