Hi Tony.
I have had a couple of similar bottles with what appear to be a mixture of Whitefriars and Walsh Walsh features. One had Triplex weight canes mixed with '7/6' canes, usually attributed to Walsh Walsh and Arculus.
I think these pieces were made around 1950 when Walsh Walsh closed, and some of their workers moved to Whitefriars and kick started their paperweight ( and related object) production. The close collaboration between Whitefriars and Walsh Walsh in the late 1940s in their lighting department is an accepted fact.
