Browning .30 Cradle e6160, British Shermans

[Alex van de Wetering]

My question regarding info on the .30 cradle, led to some interesting discussion on the fitment of .30 vs .50 machine guns fitted to the turret roof of British and Canadian Shermans during WW2.
I have no written evidence, but purely based on period pictures, my observation is that US Shermans in NWE almost exclusively used the .50 on the turret roof, while British Shermans used both .50 as well as .30.....and a lot of pictures of Canadian Shermans don't show a turret roof mounted machine gun at all(?).

Attached are two shots of the Overloon Sherman Crab with the e6160 cradle fitted to the roof. Both pictures were taken shortly after WW2.
