Thanks, I've googled again but found nothing. Previously, I googled for it and the only thing I found was a leaf shaped silver plated dish on ebay.
I remember, it was definetly part of a set as it was sitting next to another item with these handles but the liner and something else was missing so I just left it. More likely to be a suger in that case, probably.
Perhaps Sarreta is a tradename for the company and the "S" is the initial of the firm, rather than the "S" for Saretta.
