West Germany pottery glazed jug mark identification

I picked up this beautiful jug. I cannot however find the maker it has a distinctive mark. There are a few online that are the same but don’t have the mark. Any advice appreciated.

Can it be Strehla? At the bottom the brand name Strehla is imprinted by means of an ink stamp (at times indecipherable), surrounded by a kind of hexagon . Quite often ‘GDR’has been indicated. The serial number of the vaseusually consists of four digits and is imprinted at the bottom. Strehla seldom put a sticker on its produce.
