Epiphone Sheraton Gibson

Subject:

Comments:
: I recently purchased through E-Bay an Epiphone Sheraton Gibson. Blonde, maple/birch, with rosewood fretboard, mother of pearl and abalone inlay on the headstock (vine) and fretboard (v design). There is no stylized 'E' anywhere on the instrument and the serial number (or perhaps the manufacturer's number) is printed on a label inside the Fhole but there is no stamped number on the headstock. The number inside the Fhole is: P49415 8817. Could this P represent a Philadelphia produced Epiphone from 1958-1960? The Epiphone has two nickle plated humbucking in black saddles. Tuning pegs are gold as are the bridge and bolted in tailpiece. The bridge and tailpiece are somewhat corroded which suggests some age? : Can anyone help me with this?
