Featherston Camp Trumpet band opinions please

[ukbrits]

Hi Gents,
I have a Featherston Camp badge which I need an opinion on it's authenticity please.
It does appear to be different from Geoffrey Oldham's badge in his booklet -
Military badges of New Zealand.
The voiding on the crown does appear to be completely different than the one in his book.
This one does seem to have 2 small holes for the voiding in the crown which makes me suspicious
I would like to know if it's a dud or a reunion piece or a genuine badge.
Many Thanks in advance
Colin
