Help with unknown Chaplains Badge

[Milmed]

Hi,
I have been told by various collectors that this 3-piece badge was worn by chaplains duing the Boer War. Could someone confirm this or possibly identify is origin and use.

All 3 pieces are of white metal, very thin but quite strong. Attachment via wires. The cross badge appears fairly regular on the market in South Africa, the Victorian crown less frquently and the wreath is almost impossible to find.


Regards
Steven
