Silver spectacles case?


I have been commissioned to supply a sterling silver glasses case. I
would rather source one from a manufacturer than hand make one. Does
anyone know of a manufacturer of silverware who might have one in
their range. It must be plain un-engraved and curved not square
corners. I have looked on the internet but could only find antique
ones for very fine spectacles. The measurements are about 160mm long
60mm wide and 35mm deep. Any help much appreciated.

Thank you
