Rare series 2

There is a '71 E type on Ebay that the seller claims to be one of only 16 built in 1971. He claims documentation. I have a '71 and its car number is 2R14639. Could this also be one of the 16 built along side the first series 3 V 12's? Can anyone help verify this?

Where would 2rl14745 fit in the scheme of things?

A correction on the number on that last post, 2RL14745, 71 roadster.
Thank you for any information.
