Hi,
One possibility for this set is Davidson. They made a covered sugar (No 157) in this ivy leaf pattern.
In my list of glass in storage I have for box 34 (which is buried deep in may garage) 'Davidson ivy leaf sugar and cream'. What I cannot remember is whether I wrote Davidson because it has the lion trademark or because it's similarity to the No 157 covered sugar. Unfortunately It will be a while before the archeologists unearth box 34 for me !
Regards
Chris
