This AMI Record Belt Guide Assembly came from an MM6 mechanism which I parted out in August of 2017.
It is in good condition.

I believe the same assembly is found all models which used the model 1100 mechanism, including the
JAL200, JEL200, JBM200, JAN200, JAO200, MM1, MM2, MM3, MM4, MM5, MM6, TI1, TI2, R74 and R80.
