Hi Callum, The "bump stop" is the rubber that surrounds the focusing screen. When you take the lens off you will see it at the top. They like to deteriorate and go all gooey in time. If your mirror is sticking there you will probably see evidence of the goo around the edges of the mirror itself .
When this happens, the same thing is likely happening to the seals that engage the film door (bits sticking to the door edges that engage the slots in the body where the seals reside. There is a guy in the U.S. that sells seal kits (very reasonably). He used to sell on eBay but gave that up due to too many run-ins with fraud, etc. But he still sells the kits. They come with all the instructions for doing the replacement yourself. His email is: jon_good...@yahoo.com Hope that helps!
