Got my replacement door today! Very nice, and fits perfectly. Thanks very much for the tip, Belle!
What about the battery door? I’ve got a 6 screw large black russian (the type with the green guts, knobs and switch) and I would need a door for this. Even if not available, could somebody post a picture of what the door looked like?
