Might be fixable. Some years ago I had the same thing happen to a nice Birmy gun and Jack Rowe sent the hammer to a good tig welder who added new material and Jack filed it to shape. Lots of shots since then and working fine. Do everything possible to repair the broken hammer. Making a new one and getting it properly adjusted is difficult.
