Prototype Ultra Magnus or Optimus Prime Test Shot w. Diaclone Powered Convoy Trailer - No Copyright

This came out of a lot of pre-production Transformers items. In this case, the special item is the unpainted red cab and the no-copyright Diaclone Powered Convoy trailer. The Ultra Magnus is by all appearances a regular production version, but is included because it came together with the pre-production piece. Given that the rest of the items in the lot were 1986 and later figures, the Transformers mold of the Optimus cab, and the inclusion of the trailer, this is suspected to be an Ultra Magnus pre-production. The Diaclone trailer has written markings typical of pre-production figures ("T-2" and "6/23"), and it does *not* have a copyright (see photo comparison with a regular Diaclone production trailer), which makes it unique. The cab is a rounded smoke-stack Transformers mold Optimus cab, probably used in the early stages to mock up an Ultra Magnus. There is no chrome on any of the parts, including wheel hubs. This cab itself is incredibly rare and iconic, not only because G1 pre-production items so seldom show up, but also because it's of Optimus Prime. This is an epic grail-level piece, and literally one of a kind given its pre-production status.
