Large Metal Frame

This is a large metal frame (It seems to be silver plated) that measures 12 1/2" by 10 1/4".  The frame was included in a lot I purchased.  it is simple and beautiful at the same time, 4 ridges.  The backing is made of wood, looks like old plywood.  with a hinge and screws attaching the stand with the backing.  I have attached the picture of the markins which are half faded.  The first one looks like an initial followed by a name, maybe the artist?, the next word seems to start with a W, I am assuming this is the manufacturer.  There is also a marking that looks like a crest and I have included my own drawing of it due to not being clear in the picture.   The backing is marked with the number 367.
