This helmet is named for Lt. "Punch" Jamison USAF under visor cover and interior.The camo shell has a black number "6" on port side of the shell. Visor has been cutted and also visor cover has been modified. Interior liner pads are APH-6 helmet pads modified for Jamison. One side pad (cut from APH-6 front pad) is missing. I have add black cushions from my pc-speakers for earphones which you can remove easily. I bought this helmet without MBU-5/P oxygen mask, but later I managed to built correct dated (68/69/70) MBU-5/P mask for this helmet from a couple of original MBU-5/P mask parts. You can easily remove numbers of the hard shell with nail remover liquid if you don't like them.
According US article Jamison was in 1969 F-4D combat crew training. Thanks for looking and have a good day!
