Another mystery Art glass vase from Cairngorm10

Hi there,
I was hoping some of you experts out there might be able to help identify this mystery art glass vase.
It has the appearance of a french 1930's style piece, a heavy, clear glass body coated with red and brown, orange peel-like textured enamels.
The base is signed, although i cannot decipher it.
The first initial looks to be 'W'
Any information or opinions will be very welcome.
Many thanks,
Cairngorm10
