Dear Bill,
I have about 40 victory medals of Belgium (official type).
I tried to classify them by types, considering: weight, diameter, thickness, suspension ball, etc ...
Your example is very interesting for me and not common
I have only one medal similar to yours (for suspension device) but mine is not reddish.
However, I think your medal is original, and mine probably is a copy.
weight = 20,1 gr.
diameter = 36,02 mm
thickness = 2,0 mm
ball / thick wire = 4,4 mm (large)
