your item code conflicts with the item code for the 'Army of Two Ballistics Mask' mod. Specifically the 'xx000ea7' code. Either way neither that mod or this one works for me unfortunately. The esp. for this doesn't even show up in Mod Manger which is weird.

press the tilde (`~ key), and type XX000EA7 (where XX is the mod index number in FOMM)
ie:
mod 1 33 <---index num
Skull Gas Mask 34 <---index num
mod 2 35 <---index num
so, the console code for this example would be 34000EA7
hope that helps!
Cheers
edit: compatible with FWE, FOOK2, etc?
If you want to add it with the commands :
xx represents the position of the "skull mask mod" in your load order, for me its 50.
The "1" at the end represent the number of masks you want to be added to your inventory,
in this case I only wanted one.
So, to sum up my own case, I typed :
player.additem 50000ea7 1
press ENTER and you got it!
P.S. : pay attention to the space between numbers, it does matter.
