Antique 1940's Hornet Airplane or Tether Car Engine Racing Model Motor Aircraft. Good used and not working, but untested condition.

The body has dirt and sawdust and parts are missing and some are not original, the spark plug is broken, the cylinder looks clean from through the exhaust port and moves through its cycle and makes a compression sound.
