Pre-ROTJ hardcopies and hardcopy parts surface less frequently than their than Return of the Jedi era counterparts. The brown colored Han Bespin hardcopy parts seen here are cast in carbalon, a urethane commonly found among Kenner hardcopies from the Star Wars and Empire Strikes Back era. The usage of dynacast, a green colored urethane, became much more prevalent during the ROTJ era, however dynacast ESB hardcopies do exist.
The hardcopy parts are slightly larger than that of the production figure's when placed side by side. This size difference holds true for the other figure parts, which are sadly absent.
The final two images show both sides of each hardcopy part. The detail on these, and all hardcopy parts for that matter, is much crisper. Fine detail is often subdued or lost throughout the later portions of the production process. Holes located on the parts (right photo) serve as attachment points for a metal dowel. These metal dowels permit the head and limbs to attach directly to a hardcopy torso.
I've continually pieced this hardcopy together from three different sources beginning in late 2000. Sadly, the torso and left arm are still absent. If anyone can assist with the completion of this unpainted hardcopy, please contact me at michaelmensinger@aol.com.
