New Zealand Tunnelers company collar badges(other ranks)

[pukman]

Happy New Years to all.

I'm putting a few NZ badges together for Ray,a badge collecting pal from Wales.He is after collar badges for the NZ tunneling company to go with his hat badge and shoulder titles.I've been told that they wore the flaming grenade collars or the version with the grenade over NZE.Is this correct .The hat badge i have, i've matched with the plain flaming collars.Trouble is i haven't seen to many portraits of NZ tunnelers other ranks ,but have a few officer images in my files(they have their own distinctive badge)

Any opinions appreciated

cheers Iain
