Chan,
That is an Ever-Ready razor, an ancestor of the GEM. I am not familiar with it.
Is it not possible that some alterations were made when GEM took control?
It looks very much like a GEM Junior but there is a distinct difference in the Head. The GEM is hinged at the back (widest part). The Ever-Ready is hinged at the narrowest (comb part}.
I have 13 GEMs and they are all hinged at or very near the wide part of the head.
The GEM is opened by pressing a projecting tab at the centre back of the head.
It looks like the Ever-Ready is opened by grasping the two sides of the head.

That's the Ever Ready 1924 Shovel Head; GEM also issued a 1924 - very smooth, efficient razors.
