Original front apron with NSW

Hey guys, I recently met a Cali who had an apparently original front apron with INTEGRIETEN fog lights. There were rumors that there was something like this from Opel’s factory. Is that still to be found? Are there any pictures? Does anyone have any further information? Was it perhaps their own construction? But then the question would be to clarify whether and how to easily install NSW in original front … if someone here had a plan, please info. Thx @ all, BG C S
