While taking a couple of classes at Al Breed's shop last summer, his son Sam was working on a Newport four drawer chest. There are a bunch of great pictures of Sam's piece showing some construction details at Al's website, http://www.allanbreed.com/photo?exposeKeys=&xg_pw=&xgsi=&groupUrl=&xgi=&groupId=&page=12
There is little difference in size between the kneehole desk and the four drawer chest. They are essentially the same design, excepting of course the kneehole. Al sells very detailed plans for the kneehole on his website. I'm pretty sure he might be able to sell plans for the four drawer chest as well, though they aren't listed -- I'm pretty sure another student asked about them after seeing Sam's work in progress.
I'd be willing to bet Al might see this thread and respond, but you could email him. I can recall seeing a lot of photos of this chest in various places, but never any detailed measurements.
