replacement screws for the outer casing

@mordechais25274 it's a Canon so support from that company is a no go. You would depend on sellers of screw sets for your camera on places like ebay etc. I would take the camera and take it to anyone that does either electronic repairs or even RC hobbyists. Even watchmakers/Jewellers are a great resource. Anybody that works on small devices will always have some screws leftover and might be willing to part with it. Otherwise you can try some of the better hardware or electronic stores and see what they have. Use the mom and pop stores is always better than the big chain stores.
