I salvaged damaged Lumiere and 1M battle autons. They turned into autosentinels in my (traders)hold, repairing them by an auton dealer showed their weapons and armor as they were. But when used they are just ordinary autosentinels (they do not use their advanced weapons/armor)

The auton bay also turns salvaged Lumiere autons into Autosentinels. I didn't check the weapons and armor.
