Looking for reference - WWII 57mm / British 6-pound AT rounds

[Quest Master]

I'm looking for reference on how the WWII British 6-pound shells (not casings) were marked differently from the U.S. 57mm counterpart. Both shells and casing were interchangeable (British QF 6-pound 7 cwt and U.S. 57mm M1 AT gun). I'm looking for color plates, TM images, or reference photos of the AP, APC, HE or any others. I have the reference for the U.S. rounds, only looking for the WWII British ones to see the difference. Thank you.

As your question is directed at the British 6 pounder markings you might want to pose the question to the guys over at the British Ordnance Collectors Forum at http://www.bocn.co.uk/vbforum/forum.php   

 

They have many people quite knowledgeable on the British and Commonwealth ammunition and can probably answer your question easily.

Here are some photos of my 6 PR projo.  It is well marked.  The painted example is from my file of another:
