The right hand lug on one of my OM 1 's is quite loose. I'm not sure how the lug is attached to the body so I'm not sure if I can still use it to securely attach a wrist strap to the camera. Obviously, I don't want to risk my camera hitting the deck while I'm out shooting I haven't been able to find any diagrams with enough detail in them to see if its screwed to the body or riveted etc. Is it still safe to use the lug as it is, or does it need tightening or replacing? Is it something that is easily fixed?
