Possibly pre-war Josef Inwald, but I have nothing in my pattern sheets to confirm that.
I have seen a number of these here, so they were very popular in France.
I'll have a look at the Markhbeinn catalogue and see if it appears there.
I'll get back to you shortly.
Markhbeinn shows a similar vase though not identical, in the 1937 catalogue, with alternating panels of lines and lenses. Will see what else I can do to help, but imho, 1930's rather than post-war design.
