Hello JoW,
Welcome to the forum.
There was an optional sovereign mark used by assay offices for 1933/4 & 1934/5 to celebrate the Silver Jubilee of George V & Queen Mary; the mark actually contains profiles of both.
Your flask top was assayed in Sheffield in 1934/5. The makers appear to be James Dixon & Sons.
