I think it's pretty clear the OP took the photo with the rifle cocked because he wanted to show it cocked. He has said that was for the photo only, and that he stores his rifles with the bolts open. Trying to judge someone's safety practices from one static photo is impossible, unless someone posts a photo of a gun being pointed at someone else. As for storage, for Lee-Enfields, bolts open or closed is fine. I don't like leaving Mausers bolt open because then they are cocked and that DOES put some constant strain on the springs.

I'd like to thank the OP for showing us his rifle--it's a very nice looking wartime Jungle carbine. Hope you come again to the forum.

Cheers
