Yep, first Gen Mombasa. We owned that series tent. It lacked serious canvas. The walls were thin and the ladder was terrible. Never camped in the rain with ours, but yes i'd say it would need a rain fly. The one good thing about that tent is the size. It's huge. Other than that, i'd save up a little more and get a new Expedition Series Mombasa tent. The new ones are way better. Or.. offer the person $150-200 and that's it.
