NZMP

[ProCoy]

Looking for some advice as I am in the process of trying to add some NZ badges to my MIlitary Police collection, and am not sure what is available for NZ.

I am aware of the circular WW1 (also used in WW2 ??) period badge with the "New Zealand Military Police" wording and MP in the centre. Haven't got the badge yet but did pick up the collar dog.

I also have two shoulder titles, both NZMP in Brass but one straight and one curved. Not sure which period each comes from.
Lastly I have the anodised Royal NZ Provost cap badge.

Would appreciate any advioce oon which cap and shoulder devices I still need to get.
