Broken timer toaster oven (Chiswick W4)

This toaster oven has served me well but the timer mechanism broke. Someone handy can probably fix it, though the mechanism is complex (according to a youtube video). I am giving it away as I cannot fix it, and right now I’m using it by cutting the power at the mains as the oven just stays on.

This is not working and can be used for parts or, if timer mechanism is sourced, it could be repaired.
