This bowl is good quality with a mottled nature similar to WMF Ikora in nature, but much later I suspect. It has a subtle blue tinge to the rim and measures 34,5cm in diameter. It has a distinct engraved signature to the polished base which I cannot really make into anything. Part of the signature could read "Pauly" however it could just as easily end with "by" opening up Scandinavian possibilities. I would appreciate any help I can get with this long term mystery. Thank you in advance,
