Unidentified yes, but it does state probably Smith or Sharp, I guess they must have good reason for this attribution. Perhaps they are the only WS's entered at The Glasgow Assay Office for this period?
Thankyou for the suggestion, Oliver, but I was really hunting for a specific pattern name rather than a description. The design may not have a name of course; in the meantime, I shall refer to it as "Snowman" pattern.
It must of course be remembered that a lot of "One Off" patterns were coined at this stage in spoon history and many were never registered so short of finding a match.... I guess you could call it whatever you like..... 'Diball' might be a good name... Best wishes, Mike. .
In American silver, patterns with a single ball are usually called "Ball Twist" or "Ball and Twist", might suggest the unimaginative "Double Ball Twist" for yours.
Since the snowman is upside down, and this inversion of an iconic symbol carries an accepted association, think you have no choice but to officially christen the pattern - "Twisted Satanic Snowman"
