All the pieces are made by Ernst Buder circa. 1960 and they can all be found in the catalogue on Pamela Wessendorf's Pressglas site.
The catalogue is rather confusing, added to which they also seem to have sometimes sold their pieces on a "pick and mix" basis. This set appears to one of those, the tray (catalogue number 267) and bowl (cat. no. 435) are not shown in the catalogue as being parts of any set although they could well be going by the decoration.
To them have been added a candlestick (cat. no. 350) sometimes associated with another set of mixed pieces and a pin dish (cat.no. 580) from the set of the same number.
Personally I think the 1960 catalogue was made up from at least two previous editions with some parts of both omitted and possibly some new additional material added. It certainly makes their sets interesting as well as beautiful!!
