I am looking to purchase either the 38A, 38B or Garelli Baby Mosquito add on engine Kit for a bicycle. Each of these engines are pictured below. Please PM me a photo of what you have and a price. The seriall number on the 38A is located to the right of the spark plug coil Bakelite Cover. The serial number on the 38B is located near the 6 volt terminal of the lighting coil. Of the 3 rows of numbers stamped nearby the gear oil fill screw on the Baby Mosquito engine case, the bottom row of numbers are the serial number and will help me to identify what year engine you have.
