This is an original sealed kit
The Klingon battle cruiser K'tinga by AMT for Star Trek The Motion Picture. This is the later reissue of the kit.
This variation of the Klingon ship is pretty dynamic looking! Please note, this is a vintage kit and no longer in production. Boxes may be have shelf ware due to age. Decals may be unusable. Replacements are simply not available. Although it is factory sealed and believed to be complete, it is sold "as is" and cannot be returned.
