Reproject raster without projection info

$

I’m pretty new to gdal and got a presumably easy question for experienced gdal users. My problem: I have a raster ascii file of which I don’t know the projection or epsg code. However, I want this raster to be projected in epsg 32663 (WGS84).

The information I get from gdalinfo contains the coordinate origin and the corner coordinates:

enter image description here

I tried directly assigning a projection with gdal_translate, but ofc it didn’t work as I don’t know what else (and where) I have to provide additional information (by it didn’t work I mean the spatial position is entirely wrong when comparing with a correctly projected raster in epsg 32663).

I also tried gdal_translate with providing gsp’s (my corner coordinates; don’t know if this is even legitimate), or gdalwarp – no success. Thanks for any hint!
