I haven't managed to find the documents that may relate to the miniature patches in the previous post, but will have a better look on the weekend.
However, in the meantime I think it is worth re-posting this image that was posted by Puk a while back.
The image is of a No.2 NZ Light Trench Mortar Battery patch that is on the back of an officers tunic that is on display at the Gore Museum.
