It is difficult to make out but it looks to me like the decorative pattern is consistent on all the pieces. The repeated "star-burst" with geometrically produced lines crossing at different angles joining them look very similar on all the pieces, including the pin dish.
On GTS the bowls and candlesticks also look the same. I wonder, as the 1860-64 set was produced over quite a long period, could it be another one that was updated over the years as fashion changed?
Or perhaps like the 1880 set was copied and adapted by another manufacturer -- Bagley turning it into their "State" set. If that's the case, then this wouldn't be counted as Libochovice, but a Mystery??
