NZ marked sling...too good to be true?

from a surplus store called Russles in Swindon Wiltshire.

I found an image. I use to visit this store in Swindon in the 1980's but some years earlier there was also a larger government surplus store at least twice the size. It was on the same road but closer to the centre of Swindon.

I still have some of the first aid tins that were purchased from there in the 1970's, "Outfit First Aid Small For Armoured Fighting Vehicles" and also a pair of field telephones.
