Regarding Presley and Scotty Moore, Presley`s early Martin was a D18 but he also used a D28 (I don`t recall seeing a D28E mentioned by someone earlier)and I think this was the one he had the hand tooled leather case on. From Loving You onwards he favoured the much more glamorous bolnd J200 but throughout his career was seen with various other models, customised Gibsons that were basically J200s souped up and overdecorated. He used a Fender (Coronado I think) in the comeback special and in one of his films used a Burns 12 string electric. There are actually too many gitars used very fleetingly to list including a very cute old Martin in Love Me Tender.It might be interesting for somone to compile the definitive list at some point.

Scotty only had the gold ES295 for the 54/55 period (appx) from when he turned to a blond L5 with P90s. He soon changed that for an L5 with humbuckers but in Jailhouse Rock was using a blond Super 400 with ventian (rounded)cutaway. In the comeback special he was using a sunburst Super 500 with a florentine (sharp) cutaway which Presley took from him thus reducing which could have been a wonderful jam session to a merely interesting one in my opinion. Sacrilege

Obviously both he and Presley have used many more models throught their lives but these are the main ones you will see.
