I know this was asked, but perhaps not in the right context. Bought Elan II with broken film latch (the small latch that on the left that latches onto the door to close it) that needs to be replaced. How simple is this to repair, Where can I find directions on the repair itself, how much does it usually cost for either Canon or a repair shop to fix, & other than Canon, exactly where can I find the part? Several questions, but wanted to make it more precise for answers. Any help is so greatly appreciated. Thank you!
