It looks like the Libochovice pattern #1966 vase, which is shown in the pre-1958 catalogue [Source: Art Before Industry, Marcus Newhall] as being 280mm tall (can you confirm the height of yours as some patterns were made in different sizes but no variants are shown in the pre-1958 catalogue for this one... the earlier known catalogue is for the 1920s so is too early for this item.)
The registration is shown in the Glass Association Blue Book as Hoskins Rose, registered 29/4/1937. Hoskins Rose was a UK importer of glassware, and they did import from Czechoslovakian glass factories including Libochovice.
