German (?) Porcelain Vase (lamp base) by ??aureuth

Hoping my European friends can help me here! Can't identify the maker mark! Most of the mark is visible, except for the first letters. Must have been drilled for a lamp base! Initially I think the 'B' is missing, making the word 'Baureuth', but google doesn't recognize anything except 'Bayreuth'. If the name is suppose to be 'centered' below the symbol, then (2) letters are missing. The (4) dragonflies are similar, but slightly different, and are vslightly 'raised' as if the were decals. Have owned it for about 30 years, display it proudly, but NEVER have been able to attribute it to any manufacturer. Thanks in advance
