Yes, the body of Chet's 1950 D'Angelico Excel is different to the one Jim is holding. This difference became clear only after Larry posted that photo of Jim and Chet together with Jim holding a D'Angelico. Chet's guitar in the display case is electric. It has two pickups, a volume and tone control knobs, and a switch to select pickups. The D'Angelico Jim is holding seems to be a purely acoustic design with no signs of pickups or volume/tone control knobs.
BUT, the two guitars (in my photo with Jim and Larry's photo with Jim) are one and the same. And that guitar that Jim is holding is a D'Angelico.
I posted the photo of Chet's 1950 D'Angelico Excel mainly to illustrate the headstock and inlay design in order to identify the brand. This was before Larry posted that photo with Jim and Chet thus confirming the brand.
