Spy Smasher Part4 Stratosphere Invaders

The Mask's agents are planning to steal the Collins bombsight. Unfortunately for the Mask, Spy Smasher is planning to stop them! However, it's not easy to stop the saboteurs now that they're using a new Nazi “bat plane” capable of nearly vertical take-off and landing!
The choreography of the fight scene in the warehouse is a fine example of the athleticism of David Sharpe and why SPY SMASHER is a favorite among serial fans. (1942 – Republic Pictures)
