The original bridge that was on this Junior was an Adjustomatic, but it was swapped for the roller bridge that's in the photo.

The Junior 2 model started out with the neck joining the body at the 14th fret. I saw a photo of number 214, made in January of 2000, which showed the neck joined to the body at the 14th fret, like those previous to it. On this, number 259, made in May of 2000, the neck is joined to the body at the 16th fret, which is how the later ones were made. So between numbers 214 and 259 the change in the production took place.
