Looking at the GSGS M3 map, it is possible to work out a rough "correction" factor for where the echodelta site locates co-ordinates vs where the same point seems to be on the actual map.
A point we can identify on the M3 map is where the Brettorfer Str / Uhlhorner Str crosses the railroad track (Bahnweg). On the M3 map the co-ordinates appear to be very close to rW478860. If we put those coordinates into the echodelta locator for the Nord de Guerre Grid it translates to the co-ordinates: 52.96795N, 8.4491E.
Looking a Google maps that point (see orange marker) appears to be about 200 meters NE of the actual location of the intersection:

A second point we can locate on the M3 map is at co-ordinates rW466851. There is a road that looks like the letter “L” rotated about 120 degrees clockwise and the coordinates are where the short leg of the “L” meets the long edge. If we again put that point in the echodelta translator, we get a location about 200 meters NE of the actual location.

So it would appear that the echodelta locator is shifting locations about 200 meters to the NE of their “actual” locations for this part of the M3 map. Thus the grave location rW472854, that we located using the echodelta locator has probably also been shifted about 200 meters NE of its actual location.
