Yes, that large pressing ring seems also diagnostic for Swedish releases. It's the same as on this Swedish Columbia that was just uploaded:

Co FB-2538 - The labels just added are Swedish and need a separate entry. It is not UK, as indicated by the bottom legend "Manufactured
for Columbia ... London", and I've seen others with this label type and font (of the catnr) that apparently were Swedish (most likely I saw them on Swedish ebay 'Tradera'). Other examples are
Co(S) FB-2062 by Lecuona Cuban Boys 1938 and
Co(S) FB-3096 by Victor Sylvester 1945.

Added label images with some variations

According to Eddie Shaw's DATES, it should be 1941.
