Before I received this instrument, it had been frozen and warmed too quickly a couple of times while on tour in the early 70's. More likely, many times. The previous owner had a bit of a "who cares" attitude towards his tools of the trade. The cracking on the guitar looks very much like what I call the "orange peel effect".

      Hi Don, Yes, WR Smith s book is very excellent about japanning - but he doesn t mention what went into the sauce to make it look like leather - many times it

        Hi Don,

        Yes, WR Smith's book is very excellent about japanning - but he doesn't mention what went into the sauce to make it look like leather - many times it was a chemical process, sometimes a physical process such as dabbing more paint irregularly.

        David, You re correct he does not say anything about that. I wonder if it would be Tung oil. That s the stuff for making the crackle finish. -- 73, Don, NN8B
