This is a Bulgarian made flying rocket model. The manufacturer is unknown. The model has a Kraft paper body, fibreboard fins, balsa nose and a paper parachute. A solid propellant rocket motor propels the model, and then at the end of the vertical flight it forces the release of the parachute. The model is then retrieved and can be used again.
G. Harry Stine donated the model to the Museum in 1973.
