Harry Stine Shock Lock Patent

This is the approved patent for G. Harry Stine's Shock Lock or shock cord retainer.
This one goes back to 1970 when he was with MPC.

I remember seeing these first in the old Minijet kits.
It's a simple and clean design.






Page two is interesting. The drawn model is the old Dirty Bird design with a plastic fin unit from an old fireworks rocket. I wouldn't expect to see this unit in a model rocket drawing from 1970.
