It is certainly a Czech / Bohemian style, but I suspect yours was made at Pilkingtons, St Helens, in the 1960s. I believe that some Czech workers came over and made a range of flowers, butterflies and so on in a rather blue-green or yellow-green glass, with designs in yellow / orange / white rod and frit. I have a butterfly and a flower, and have seen several 'name' weights. All had a rounded base with recessed, broken pontil mark. The older Bohemian versions tend to have clear untinted glass.
