Yes. However, that's not necessarily bad for an officer's / private purchase helmet. He may have changed regiments and used the same helmet. To me, judging from the crazing around the holes and the color of the leather, these may be legitimate since both have the same 'patina'. ON the other hand, if somebody picked this up right after WWI and tossed another eagle on it, then that's not good. You'll really never know which is the case. ON the OTHER other hand, there is no obvious imprint from another plate that I can see, so that's a good thing...
Ron, Grenadier helmets changed Wappens starting in 1888. kaisers bunker lists the dates in the the link below. So the change to the new eagle explain different holes. For EM helmets, the makers tried to make new grenadier eagles to fit the old holes, but they did not always fit. Officers would get what they get. Unless a grenadier officer was made after the date of the eagle change, you will usually see double holes.
