I have 1 fighter helmet, good-VG cond has all electronics and nice shield, date of manufacturer 6/67 model HGH-2, made by gentex corp for the USAF size medium.I also have a clear visor for this.
2nd helmet is aSPH-4B helo helmet, size large with all electronics, dark visor, mounting on visor cover for NV mount. Made by gentex corp.
Both are $150 shipped each. If someone buys both I have a US army tanker helmet , complete but needing a full restoration I will throw in free. Selling to give some cash to a good friend for his kid for Christmas, my gift to him so he can go buy junk toys for his kid this year. Could make the start of a nice helmet collection.
