Do you know is the leatherette is removable?

Thank you for this. I think I must be crazy doing this as my first camera repair attempt. I had dirt and oil all over my shutter blades and it was jamming every shot.

I managed to get through every step... until... Trying to resolder those short wires to the mirror box (the ones with the metal ribbon amongst them, near the frame counter). If you have any tips on actually managing to do this it'd be much appreciated.
