sorry to say this, but it looks like a repro / fake to me. The corners of the front visor are too rounded, the neck guard doesn't have the characteristic inward curve to the trim along the side of the neck, the liner looks bogus.
A real officer's GDC will be flexible and thin, so much so that when it rests on a table, it will be able to 'rock' back and forth a bit.... which is somewhat alarming.
I'd tell your friend to steer clear of this one.
