Hey Drew, how's it going. Actually, I'm not the one selling it, I just have have it up for sale for a friend in GR. This is the list of missing parts he sent me.

It is missing: the PA System, the Flag Pole Assm, the Purge Valve, both Deck Vehicles - I do have the Tow Hook piece, Keel Haul's Pistol and File Card, Arrestor Hook. The light grey pieces do have sun yellowing. No directions. Decals are all fairly good. The box is pretty solid, crinkled down on one edge (needs to be sprayed with neutralizer).

He is asking $450 for it. I'm pretty positive he will work with ya on the price. Feel free to ask any more questions if you have them.
Thanks,
Torrey
