Bootfair Find pair satin glass vases ID help please

Hi Folks,
i found this pair of Satin glass vases at the local bootfair this sunday.
No idea of where or when made.
I was drawn to there landscape effect colours to start with then when i picked them up felt the satin finish and thought them lovely.

Cut top rims and flat base so i guess mould blown.
Clear inner with colour layer at center and cased in clear again, any thoughts or ideas appreciated.
Thanks for taking the time to look.

No idea who made them, but is the base of the vase engraved '11/6' or is it just my imagination?

Hi, just had a look and its a mark which i think is written in pencil as 2/11
Pre-decimal price perhaps ???
