Tascam 238 FF/RW drive plus idler

This motor was from a Tascam 238 , I am selling the motor but it will come with the idler assembly, I do not warrant the little tyre that's on there, but as no one has ever asked me for one its maybe not one that goes to mush , I will get some in if I hear and different

I cannot see a part number on this , and I am not certain if this was only used in the 238
