I have seen 50s pictures of Elvis playing a Martin D28E, and a sunburst Gibson, probably a J45 or 50. Scotty Moore played Gibson - I think a model 295. In the 50s it was common to take the maker's name off the headstock (or cover it with tape on the BBC) to prevent free advertising on TV. A Paisley Telecaster is a standard Telecaster which has a Paisley design decal on the front - Paisley pattern was very fashionable in the sixties, but most people stuck to Paisley shirts. The design has a certain popularity, and has been re-issued recently - my local music shop is currently trying to sell a Shocking Pink Paisley Stratocaster - you need shades to look at this thing!
