Very few of the F.21's had contra-rotating props.
Most were Griffon 61 or 62, the contra's used Griffon 85.
They were more likely to be found on the Naval versions (Seafire 45/46) to counter the massive torque.
Main use of contra-rotating props was on the Seafire 47 which were fitted with 2,375HP Griffon 87 or 88.
