Hello
Can any one help me regarding a ww2 pith hat I own, once belonging to Lieutenant Colonel James Ferris Fuller.
#6069.
I understand he commanded the 2NZEF's Dental Services overseas in WWII.
The Pith hat I have with his details inside looks to have had a patch pined on at some stage.
As per the photo's you can see pin marks on the left hand side.
I would like to know what it would/should have looked like so I could possibly replace it.
Green Square? Green / White?
A picture would be great but any help would be fantastic.

Cheers
Corey
