Here's a quite uncommon piece from Jobling's Art Glass range: The 2585 Pickle Jar and Lid, as shown in the 1934 Trade Catalogue.
This pattern doesn't turn up very often. I've seen a handful of opalique versions -- both frosted and non-frosted -- plus just one 'flint' (clear colourless) example which I have in my collection. According to the catalogue this shape was only available in either opalique or flint, though there may be other colours out there. Whilst usually sold as a lidded jar, I have once seen an opalique example with a flanged (flared) rim which presumably was intended for use as a vase.
A very similar design, again as a vase with a flared rim, was made by 'Etaleune' (presumable a Leune mark). An example can be seen here:

I'm not sure why both are so similar -- it could just be plagiarism or they could be from the same designer as it is known that Jobling purchased designs and moulds in France and were also said to be in contact with a French firm in the Alsace-Lorraine area who shared design sketches and samples with them (see Baker & Crowe p. 57).
While my flint example is marked across the base with the registration number 796182 (which corresponds to a registration date of 6th September 1934), this opalique one is marked 'Regn. Applied For' suggesting it is early production made before the registration number was added to the mould.
