I wish I could know how many shaded top OM 18 guitars were made and perhaps many is not an ideal word choice. I wonder how few were made. I estimate… hardly any. There is one here, this is a nice original example with some pick wear. I was thinking it had no repairs but I did find a 1/2 inch square patch on the side when I looked under black light. It is a few inches from the end pin. This is a nice intact example.
