I believe you are right NPN sound right, You can do a search on "2n2222 +pdf" on google and check the datasheet, my plug in is not working so I couldn't verify this!
Notice that the positive of the 4.5 battery pack goes to the motor. and the negative on the motor does to the collector (c) pin on the transistor.
I keep forgetting to label and use the right colors!
