Other differences include the route under the bridge p-90 which in very early 1952 Les Paul models, has the wire channel passing thru the pickup route in the center.
Contrast this to 1952 models with neck binding which have the normal wire channel route through the treble side of the neck pick route.

Photo shows the much more common clover leaf cavity pattern found on later '52 Les Paul models and until today.
Additionally, early 1952 Les Paul models also have different wood routings. The control cavity is a square like parallelogram shape, instead of the cloverleaf shape used on 1952 models with neck binding.
The rear control route was change in 1953 around serial number "3 22xx". The trapeze tailpiece ground channel route was discontinued. This route was used for the ground wire running to the claw of the trapeze tailpiece.
The conversion from trapeze tailpiece to wrap-around on the 1953 Les Paul started at earliest around serial number "3 13xx", so early 1953 models still use the older trapeze tailpiece.

In this photo, the Gibson logo of a later 1952 Les Paul shows clear separation between the "G" and the dot of the "i".
The beginning of the Les Paul would see several subtle and not so subtle changes that would separate it from all other Les Paul models produced in 1952 and beyond.
No one know for sure exactly how many of these very early models were produced. Estimates run from 12 to no more than 100.
The different features of these early '52 Les Paul models include no neck binding, two pickup mounting screws positioned diagonally on the corners of the bridge P90 pickup, the logo often has the "G" touching the dot in the "I”.
