Everyone is correct from the above posts. I believe that the earliest the controls started getting
mounted flush to body itself was probably '74. I have a '73 Celebrity which does indeed have the
2nd scratch plate (P'guard) and there is a PIC of a '74 with the controls mounted on the body itself.

I love the celebrity and this one with humbuckers and those great shallow 70's necks
is all you need. These are heavier and feel more solid than the 60's ones.
