A kv128 stormsurge, aka big robot chicken with a big gun. Included in this listing is the aforementioned chicken along with its related bits left over after building and the building instructions. 
Model is in good condition and fully built. As a warning its relationship with its base is a bit rocky and the feet may separate from the base in transit. 
As such, I'll include a couple of magnets with this so you can see if that will work better than trying to glue it when it becomes yours.

Please reach out with any questions you have about the item, have a good one!
