Duke of Cornwall's Light Infantry

[Stma]

Hi,

Would anyone be able to advise if this Duke of Cornwall's Light Infantry badge is real or a copy / fake?

There is a crimp mark on the slider but perhaps it is not genuine as it might be made of the wrong metal (due to the green oxide / stain on the front)?

Many thanks

It's fine but just needs a light clean.

Many thanks for info and advice.
