It certainly looks like the one in the rather blurred photo. There are so many variants to view!
Would the British Army, with the Polish have deceided just how the MSO badge would have looked, and where they would have had it manufactured? I think it might have been too early on after the war for the Russians to have a say in the design???
I know the Russians objected to certain aspects of the naming of parts of the MSO in later years when the British were setting up ie. the Transport Units etc.
