I'm cleaning out a long closed Western Ma. luthier shops inventory  and will be selling a lifetime collection of mostly vintage musical instruments and parts. Today I have a   Black wide bevel Gibson archtop guitar pickguard . This was marked L-7C . I have no way of confirming this , but what I do know is that it indeed is vintage Gibson . Here's what I can say. The guard has been notched for a floating pickup, the  bracket block is missing, and there is one control hole drilled  in it.
  I hope some luthier out there can find a use for this.  Be a great way to electrify a vintage  Gibson archtop guitar without destroying  the original pick guard .
