Hi Doug,
interesting post that gives me some doubts. My 2007 Besson Prestige 2007 German made registers the following weights:
5,2 kg stock out of the case
5,645 kg the way I play it, with mouthpiece, lefreque, lighter caps and heavy bottom cap on the 4th
5 kg removing lefreque plates, water catcher, hand strap, mouthpiece and plastic main slide guard.
By removing the pistons, caps, springs and trigger, 4,360 kg of brass plate alone remain.
Considering that the bell has a brass plate thickness of 0,6 mm (http://www.dwerden.com/forum/showthr...etal-Thickness), how can it be possible that the Adams E3, with a plate thickness of 0,7 mm ( constant throughout the bore) is so lighter? Making a rough calculation there should be about 700 grams more on the E3, instead it is the opposite.
