I do not have manual for this so I dont know for sure the number. The Death Star comes with the original large manual. It has a page that has came loose.
This is an amazing build! S when taking apart I found ONE piece that is missing and replaced with a close relative. There are supposed to be six small dark blue cylinder pieces and I have 5.
In its place is a blue piece. The item "Lego Star Wars 10188 DEATH STAR 2008 Minifigures & Instructions PLUS Tie Fighter" is in sale since Saturday, May 29, 2021. This item is in the category "Toys & Hobbies\Building Toys\LEGO Building Toys\LEGO Complete Sets & Packs".
