"It is a 1962 Tempest, not a Lemans.. "
You are correct. Further research revealed that in 1962 the Tempest had an option package called LeMans as stated in the review at http://www.cargurus.com/Cars/Overview-c7642-1962-Le-Mans.html
Maybe this one has a LeMans package or maybe not, but it is definitely a 1962 Tempest.
