Mattel 1956 GUERRILLA BURP Cap TOY Gun Hand Crank Army Camo (RARE)

  
Have no idea if this item works or needs to be repaired. The crank does operate but the cap metal part does not turn.

I might be doing something wrong. I have no idea please ask questions for more information. Inside has corrosion as shown outside is in really good condition with minor wear from age, if you have any questions regarding this item or need additional photos, please do not hesitate to contact me.

This replica gun contains the colored markings required by law, including a permanently attached orange plug.
