Seeking Armoured O.Ps. and Brens

[Lynn Eades]

Hi! Guys. (generic)
This Kiwi would like to know of the existence of any other carriers of the "O.P." variety in particular the "Carrier, Armoured,O.P, No1, MkIIIw. (T84991) I am in need of detail of the observers shutter, the mounting of the oil cooler, and the air duct at the rear of the hull. (as well as the many small parts I am looking to procure)
Any info will be appreciated, including guidance toward any publications specific to this carrier.
Second question. Do any Bren carriers still exist elsewhere?
(proper ones I mean, as in " Carrier, Bren. No. 2, Mks I and II.
We have two here in "Godzone," but I've never heard of any others. Please advise. ......Thanks
Lynn Eades.
