Analog film photography and cameras

My sister had one BITD that was used and abused so I got good at XA repair (that was 15-20 years ago when my hands were steadier and eyes keener).
As you might imagine, things are tightly packed which can be intimidating, but it's nonetheless designed to be repaired so it's doable.
Do some background reading first - find a repair manual or look at some online teardowns etc to familiarise yourself with what you're doing

I think I will look for some instructions how to take it apart and clean - anyone else done this?
