Snake Glass - Who made it?

This glass with its lampwork snake in a hollow foot with 8 facets is probably Bohemian 1920-40 but who made it? The snake is lime green with dark spots.

Glasses by Jules Lang & Co, UK

I have about a dozen of these all the same shape but with two differing wheel cut designs, one very deco and the other more traditional. Some of the glasses, not all, have a registered design number 807128 which was registered on the 14th October 1935. An Internet search revealed another bowl by Jules Lang. They were not included in the book “British Glass - Between the Wars” but were obviously active then.

Dealer Tony Hayter reports, “I have sold about six different pieces with Jules Lang registrations. He started off in London in the 1880’s in partnership with Jonas Lang and their first glass registration (and the only lozenge one) was in February 1883. They were based in Charterhouse buildings in London and were listed as Pottery and Glass Merchants. I believe that they were only retailers and based on their glass that I've handled I believe they were importing from France and registering the designs in England.”
