One further point - the dimensions of the "bulge only" on the smallest device - the one with the ruler scale as seen in the images indicate the bulge is 7 cm in length and about the same 7 cm in diameter or ~260 cc in volume, maybe more. That is without the long flanges.
If one trusted observer (namely Levi) were to have been given a quick peek inside the original device, back in January - and then included the flanges in his rough estimation of the volume - then one liter as a rough guess would not be a surprise, since the heater makes it appear more voluminous than it is. Jones Beene wrote: Everything seen so far - when exposed looks nearly identical, and the only reason to suggest that there ever was a larger model is for Rossi to hide the fact that the erroneous results of the January test (Focardi tribute) where 'wet steam' was giving three times more energy than actual.
