Repaired and re-sized version of the photo:

The centre guitar is indeed a Gibson ES-330TD.
Earliest versions (1959) had dot fret position markers and black plastic dog-ear pickup covers.
The dots were replaced by small block markers and the pickup covers were updated to metal (nickel-plated) ones from about 1962 onward. This example, therefore, appears to be a 1961/1962 transition model with the newer block markers and the original plastic covers.
The block markers look better and so do the later pickups, IMHO.
