I think they removed the 767 seat map because no two 767's are alike. I've been on 4 IAD-MXP-IAD. No two were alikesome cloth seats, some leather seats, 2-1-2 seating on 3, 2-2-1 on one of them. different color interiors, different seat letters, different number of rows. the GA's did not have a correct seat map either. One of the set of seats were very uncomfortable to me.
all had close to 60" between rows, very wide aisles. Decent food, decent wine for c class, had better, had worse.
inter europe c class is just like y class with a slight up on food and empty seats around.
