Look at the doll's head rib extension.

You will see that the front section does note meet exactly with the corresponding part of the action. this shows that it has moved back wards when the gun was re-jointed.

It is not usually a problem unless it has happened repeatedly and then it starts to look a bit gappy.

I would expect a gun of this age to have been re-jointed. It is still a good gun and still a good buy for what you paid.
