Viewfinder extension for GOMZ-Sport

Some time ago I have found a GOMZ-Sport camera with very uncommon viewfinder extension.
It seems to be professional made, but unfortunately I have no information, whether such extensions were made by GOMZ.
May be it was simply made by some photo-enthusiast .

This excellent "extra" part is certainly made by a leathe expert. It is ot original for sure. It is applied in this camera because the original owner should have a near sight vision and the piece corrects the focus without the need of an extra lens.
