I bought a used OE 30 at local Guitar Center friday.$129 used.In excellent shape no scratches,dings or marks.Cherry Red finish looks hardley used.Plays great.My questions are: 1)Has anyone seen an Oscar Schmidt OE 30 without the Delta King label on headstock? It also is one without the OE 30 on the headstock.But i have seen some with OE 30 and without.No country name where made.No engraving on bolt on neck coverplate.The label inside body says OE 30 CH serial IS 9120077.Any ideas when are where made.Thanks for input.
