Sorry I don't have any pictures for you, but one easy way to tell is that their is small blue writing down the length of the black sheath that covers the cable both long and short. It should say "teleflex covered by US and Foreign patents" which is repeated the whole length of the black sheath covering.

Their also seems to be a unique way each end is crimped to the black sheath, where most repos that I have seen do not have this type of crimping.

Lastly, I have been told (which I am not sure if this is true) that the original long cable will spin 360 degrees inside the sheath whereas the repos do not??????

What is the total length of the long and short cable you have, furthest point each way??
