This gonjo has probably been fitted by the gonjo around the pesi being punched . I feel that a key in keyway fitting would not have been used, and even if it were, I believe there would be evidence of the gonjo hole being tightened by punching.

It appears you are talking about different quality levels of manufacture but I don't understand the different techniques you are discussing.
