I've been a machinist for 4 decades and I don't believe the aluminum body is stamped. In step seven the interior of the back has multiple steps machined. The exterior shape would be impossibly hard to maintain during a stamping process. And further, aluminum is notorious for breaking and cracking under pressure unless closely controlled heat is applied. I do wonder about the phrase "all aluminum body" because of the plastic pieces.
