two tone helmet net on M1 helmet

I have had these nets for a very long time and never noticed they were two tone green/black.
Could these have been manufactured in the UK during the war ? Anyone have any information ?

I have since heard that these two tone green and brown helmet nets are Canadian WW2 issue ? These two tone nets were also used on M1 helmets issued to the 13 Cdn Inf Brigade before landing on Kiska Island during Aug 1943. Anyone have any additional information ?

I believe the two tone ones are Canadian.Have seen them on M1s and Common wealth helmets

If you have any extras for sale I would be intrested.

Thanks
