Not likely any connection with any European maker. The only Greener style "round sliding" bolt gun without functional underlugs I can think of is the 200E Merkel over under. It seems to be someone's effort to get away from the chore of fitting the rotary bolt. In the late thirties, Remington considered using Fox actions for a "Parker reintroduction" after the Parker operation was shut down. Remington would be hard pressed to pass off a Fox as a Parker if the rotary bolt were present. Remington memos discussing the use of the Fox do exist, but I am not aware of any prototype. I believe that the Lancaster Trigger Company was out of business by the late thirties, but a gun with a Lancaster trigger could have been used as the Parker-Fox prototype, I guess.
