Thank you for your thoughts and responses.
Anne thank you for transferring the pictures. There are no other images on this site with glass that looks like my bowl either with the same trailing or the finish, searching under Gordiola. Nor are there any under searches for Mallorca, apart from one candlestick which bears a vague similarity and which I believe is attributed as possible La Fiore. Likewise I did not come up with any other images searching the net or the Gordiola site, that have this bowl or finish. So please feel free to leave the pictures here as it may help someone in the future.
For some reason people seem to be disappointed by a Mallorca attribution - which is unjust if you've seen the prices in their showroom. Personally I am delighted - this bowl cost me £4.00. Thank you.
