 * If you pick this armor up while doing the quest You Gotta Shoot 'Em in the Head the game confuses this for the T-51b Power Armor from Fort Constantine and completes the mission. It's confirmed on the 360 version that this also rewards the player with the Achievement.
 * You can sometimes wear the Ghoul Mask, Shady Hat and various other head gear while wearing the Winterized T-51b helmet. When viewing your character externally, however, you'll only be wearing the helmet, whereas your inventory will show that you are wearing all of them.
 * Moreover, if you complete this quest before you have progressed the story far enough to have acquired Power Armor Training, you will be able to wear the T-51b Power Armor anyway. Once you do, you will be able to equip all forms of power armor, including those dropped by the Outcasts in the facility and the ones dropped by the Brotherhood of Steel.
