Missing lever trip or spring or both. Yes. No. Remove the bolt from the center of trigger plate. Anything fall out? No. Can you push anything out by inserting a punch, nail, paperclip thru the extension slot topside (have to push the lever right to get the rotary bolt out of the slot)? IF you push out a small wedge-ended piston with a hollow base but no spring, you're home free as you need a light-gauge spring which will fit in the base of the piston and can be trimmed to length. If nothing falls out, you need both trip and spring and will have to find someone who's parting out a Fox and buy or borrow from another gun and fabricate.
