That you can tell from where the wire is attached to the commutator by counting how many are attached to the commutator.

As for the number of turns...if it is not written or stamped on the armature then there is no way to know short of unwinding the motor.

There is a way but you will need a special LCR meter (some multimeters have this capability built in) and a jig that you can easily make. If you're really interested you might search through the Big Jim black book forum on HobbyTalk or later the RCCars forums as I know Big Jim did a posting a number of years ago explaining the procedure.
