Centurion helmet (Fallout 76)

The centurion helmet is a headwear item

Characteristics
What was once an old diving helmet, the centurion helmet has been tricked out to look like the headwear of only the finest Roman soldiers. It has a large ornamental crest made out of a broom bristle.

Locations
The plan for this helmet has a chance to drop from A Colossal Problem as of the Fallout Worlds (update).

Previously, this was unlocked at overseer rank 73 when Nuclear Winter was available.
