11/44 ROF(F) No5 MkI with MkII rear sight

I don't really think that's the case...

There are more reported miss matched bolts there than here by a long way.
I have nearly been shot by a person whose safety practices were bad and did not improve with tuition , just brainless and Dumb. ADs are no fun at anytime when you are the RO or trainer and even less fun on a returned firearms first outing on returning from a gunsmith. I consider all firearms to be loaded until i have cleared them and consider cocked ones even more dangerous.
