I found these motors among my “stuff” 
They were an incorrect supply I received for a job about 5 or 6 years back, but I thought I would bag them up, as some folk may find them a useful low cost motor for scratch builds and kit bashing.
They were sold to me as 12v motors. I have tested a few and they appear to be around 20,000rpm at 12volts and lowish torque – so think about the power of a black stripe Scalextric motor, but can end drive instead of bell end drive like a Scalextric, and with a smooth shaft like a hobby brand motor.
