London Irish Rifles Chevrons
 

I'm looking for the correct chevrons as worn by the London Irish Rifles in WW2, to represent those worn by an Uncle.
I have a pair of Lance Corporal in a wide black tape on dark green, and two others of slightly different styles also in black on a VERY dark green backing.

Are any appropriate for WW2 London Irish Rifles, or if not, can someone point me in the right direction?

Thank you
