The T64 (& CT64) held the longest-duration-production record for a GE jetmoteur - roughly 1958 to late 1990's. And it rotates backwards i.e. clockwise viewed from the front.
That production record has been recently broken by the TF39/CF6 family, 1966-present; CF6's are still produced for the C-5M re-engining project. CF6's turn the right direction.
