S3D Field sequential Spacehunter wanted

[E R Swanson <ers@xxxxxxxxxxxxxxxxxxxx>]

I'd like to get a first generation copy from the Japanese field sequential
videodisk. I have two VHS copies of the film-- one that has good sound has
a dupey looking picture, and the one from 3DTV Corp (at least the recent
versions) that has a good picture, but is missing one of the audio
channels (which makes the film pretty much unwatchable because it makes
extensive use of both stereo sound channels). And even the 3DTV Corp copy
doesn't look like a direct dub from the original, but made from an
intermediate video copy. Does anyone have a functional Japanese field
sequential disk and player? I'd pay or trade for a sharp copy. 

Or, does anyone know someone in Japan who has a copy of the videodisk that
all the VHS pulls were copied from?

Thanks, Elliott
