Ned, you're a star mate. Thank you for explaining the RGJ story for me. It really gets all confusing when one takes into account how many different units were amalgamated after the war.
I'll stay away from the Commonwealth stuff for now. Any given regiment can have many different cap badges, one for officers, one for other ranks and then don't forget about everytime a new monarch ruled.
Thanks also for the ID on the 3rd badge!! At least I now have a direction to my search.
