I have a 32 DA 4TH model top break. I mistakenly let a friend look at it and now it fails to double action. It will single action ok. I can pull back the hammer and fire it. But it will not rotate the barrel. When u pull the trigger by itself it doesnt fire or move barrel and sometimes the trigger will get stuck. I can take pictures of it with side plate by hammer removed. To show gut of gun. Also i can use a small screw driver in a particular point just behind the arm that spins the barrel and it will Double action just fine. I cant figure out what broke or what if anything is missing. Please help gun been in family since 1888. Was my grandmothers purse gun. Would love to have it in working conditions again.
