T&T Productions made a bunch of great TV and Movie resin model subjects in the early-mid 19-90s.
This kit includes the upper hull, lower hull, rear fin, interior tub, decals, a photo of the model assembled, and some other small parts.
The lower photo shows this kit compare to the Polar Lights plastic (1:32 scale?) version. Noting that their resin kit is larger and is not a copy of an Aurora offering it appears.
T&T also offered a 1966 Batmobile among other George Barris creations, TV, and Movie. Some even in 1/16 scale.
