Man I gotta get me some of the old Kyosho catalogs, awesome pics.
As Joel said, the belt drive was an upgrade offered by Option House. All the rear motor version Optima's from the original Optima up to the Optima Pro came as chain drives.
I have a nearly complete Turbo Optima project myself as well as a NIB one, seeing those pics makes me wanna get my project's body painted.
Keep us updated with the strip down and rebuild.
