D'Angelico Excel/New Yorker 1963 Blonde

There is some disagreement as to what model this 1963 D'Angelico actually is. Mr. D'Angelico's logs call it an Excel, so maybe it's an Excel. It's a 17" body and it has some Excel features but it also has the New Yorker headstock inlays. Why put the New Yorker inlays in the headstock if it isn't a New Yorker. It doesn't say New Yorker though. No matter which model it actually is, it's a stunning guitar and a piece of art. It's loud, too. I don't associate arch tops with volume. It has a very sweet sound with good balance and strong midrange. Condition is near mint. I am not an expert by any means so any knowledge you might want to impart will be appreciated (I have the book already). Nice fake alligator case (no alligators were harmed). More (better) photos coming
