I honestly can't say that the M-D is 'fat'. Based upon your measurement of the M6, with its dial and rear door, it is actually a bit fatter than the M-D (which doesn't have a rear door, and the dial is more or less flush with the back). The top plates are certainly different, but here again, depends on how one measures the 'fatness' of each body.
