Victorian Opaline Brocade uranium glass pinched vase

This interesting small Victorian vase is made from pale yellow uranium glass with a heat reactive opalescent pattern. The vase has an unusual pinched form, & the foot has been folded back on itself - originally blown hollow to create the Brocade pattern, then flattened. Perhaps an experiment, as the result is not entirely successful - there is some trapped soot from the process.
It measures 9.5 cm tall, 9.5 cm across the pinched top rim, & 7.6 cm across the base, which has a snapped off pontil mark.
I know a few makers in England & America made Brocade patterned glass, but there's something about the quirkiness of this one that suggests John Walsh Walsh.
