M12 (M400?) production number stamp locations

[AMG Merc]

An interesting find when I delved inside my driver's door recently (the arm is recovering well!). The production number stamps we know are located in both front door jambs (near the top hinges) are also mouled into the bottom inside of the doors (I suspect to ensure that what comes out of the moulds goes together)!

Yep. They are also on all M400 dampers and various other places around the car.

Shows the care taken to ensure everything that started together stays together.
