The original 1980 line of Gundam models does not have an associated grade, since this terminology was not introduced until 1990. These kits are limited in articulation, some require glue to assemble, and they must be painted for a correct appearance. Model Kits released to coincide with a show or movie usually that did not have a grade associated with them are generally referred to as No Grade kits. These were released in 1/144, 1/100, or 1/60 scale (some 1/100 models used the High Grade name on their boxes).
