6879 and 6898....both i belive are complete,built them the other day,its possible there maybe a small piece missing but highly unlikely.....6898 does have a slightly discoloured white base plate,this is kinda fits in the middle of the set so not really noticable and easily replaced....the figure also has some hairline cracks to both his white arms,no other issues to report and anything,pretty decent condition considering 35 years old ....check out my other lego listings
