Replacement one-piece neck, lower saucer and bridge for the 1/1000 AMT/ERTL Excelsior and Enterprise-B kits. The replacement for the underside of the saucer corrects the planetary sensor array and includes the "trench" around where the neck connects. It also has engraved instead of raised panel lines.
These are drop-fit replacements; only very minor kit surgery required for use. Master patterns by Brent Richter.
