I’ve unfortunately been unsuccessful in locating a model number or production date so please reference photos fully to get the best idea of the current state of the helmet
I don’t see any major physical flaws or issues like cracks or broken pieces
Helmet has a double visor as shown
It is tagged as a size XL
From the information I’ve revived the original owner was a helicopter pilot for some type of rescue missions
Shows some signs of external cosmetic wear as shown
Some internal foam outside of ear pads is showing signs of deterioration
Internal straps and parts appear in good vintage shape with normal wear
One screw cap is missing on visor adjustment knob as shown - still operates
Any questions please feel free to ask
Thanks
Ignore
