Karre Loftheim just gave a demo on veneering the tool till at the Jan 2011 PATINA meeting here in VA. I wrote a brief article that will be on the patinatools.org website and in the newsletter sometime soon. Although the demo was on veneering the till, he talked about the chest. Dovetails are visible on the front and back of the 7/8" thick, full width case sides.
As noted in my article, he said to dimension it from the inside out, but build it from the outside in, in other words, know what size your tools are and fit the drawers to them, as well as the length of the planes that would stand in the bottom, just below the sliding till. Otherwise, things wont fit.
I saw a photo of the top and it looked like it was a framed panel that was canvas covered.
I hope to make one in the future. I don't plan to match tool for tool but I'd love to get my hands on a Kenyon back saw.
