According to Dickey, he ordered the guitar in 73' and received it some time in 74' He played it at many venues and in the studio, but always felt closer to his 57 goldie. I' parapharasing his letter. You will notice the back of the head stock has a m.o.p. inlay of the Magic Mushroom...the bands logo even today.
As for wood and construction, I'll save that for another time. I can tell you that the front of the head stock and the top of the body are bound and inlayed in sterling silver!
More to come as my time permits...thanks for your interest.
