Hi all, I was looking at this photo in the Canadian archives and realized I have no idea why there are these half-loops on top of this 17-pounder's gun shield. A local addition? I don't see them in other photos.
Can't immediately find a contemporary shot, but think this: Stock Photo - London, UK. 10 May 2015. A 17 pounder antitank gun and Morris gun tractor are two of the items on display to the public in a special exhibition of wartime hardware in St
I was going to mention it breaks up the hard straight line of the top of the gunshield. See similar on the 6 pounder's wavey top.
I know this is an old thread but yes, it is to break up the hard line but there was a Mod issued to remove them as it was found better to stick foliage in the gap between the shields instead. Later production eliminated the strip.
