C-9979 Landing Craft
The C-9979 landing craft was a large-sized landing craft built by Haor Chall Engineering for the Trade Federation's military forces, and later for the Confederacy of Independent Systems. When the Trade Federation began planning to create its military forces, Haor Chall Engineering produced a design for a landing craft that would carry troops and ground vehicles from warships down to planets.
There is a snap-together mini model kit by AMT/ERTL from 1999 in the 1/4800 scale which is a great size for SSB. It can sometimes be found on ebay.
