I am not sure if the Middle Danube map is in the series 4416 or 4116 as this reference seems to have both references (possibly a typo in one of the numbers??).

I did find another map here, which seems? to be Sheet N2 in the GSGS 4416 series ( apparently the same as AMS 641).

It "appears" that co-ordinates 023338 are on this map but of course, that may be just a co-incidence if this is the wrong map.
Oops... I should have been on Sheet N-5 not N-2, (need more coffee this early). It looks like udf_00 (see below) has the N-5 map in the series.
