I have a 40 year old Naerok 16" scroll saw going free to a good home. As you can see in the photo the plastic link between motor and saw arm has broken. I have not managed to find a replacement but for the with the skill and kit, it should be possible to 3d-print a new one. the motor is in fine working order, table rust free and flat and can still tilt.
I will be at the G3 annual show should anyone wish to collect it there.
