Those weapons appear to most closely match the Czechoslovak Zb vz. 26 light machine gun on which the Bren light machine gun was based. The Czech model seems to have the straight magazine whereas the Bren mags were curved and carried more rounds. Link for the Czeck ZB vz. 26 http://en.wikipedia.org/wiki/ZB_vz._26 and the link for the Bren http://en.wikipedia.org/wiki/Bren_light_machine_gun Brens were used by the Canadian as well as our British allies and others.
Just a brief search so I am sure more extensive information could be found.
