Well i have been into the loft to find two bowls in this range
that i have had for many years, one is signed Orrefors G U 80
The other is signed O f , either 32 or 52 then underneath G U 69
That stands for Simon Gate hand formed,i hope this will help.
embarrassment over. ps the o has the little squiggle. :spls: :hiclp: :chky:
