This is the LEGO Star Wars Venator Class Republic Attack Cruiser 8039 from 2009ish. It is incomplete and comes as pictured. There are no minifigs with it. I’m not sure how many pieces are missing. The instruction books are included.

I am happy to provide any additional pics or close up pics that you ask for.

Once sold, I will disassemble it into large sections and place them in ziploc bags, which I will then pack into a box. If you prefer me to completely break it down to individual pieces, I can do that too- just let me know.
