Alamo Posted September 3, 2021 Share #1 Posted September 3, 2021 I have a flight helmet i believe to be a Gentex HGU-33 ? ...Not much left of it but i'm going to change that.😉I found a Gentex stamp on the inside and the name Jacobs hand written too.My brother gave me this about 40 years ago, i believe it to be from the late 70's or early 80's..There's a little more to the story but i'll wait for any help you might have....Thanks in advance.

mohawkALSE Posted September 3, 2021 Share #2 Posted September 3, 2021 Its not a 33P, this is a USAF HGU-2 from the early 60s. Can tell right away by the thin edge beading and color and then the swing arm ear cup mounts. I have a 1963 dated HGU-2A/P with the same swing arm ear cups. I think this is a straight 2 since the shell itself lacks some vent holes in the top area. Thats got enough to it where it should clean up/restore nicely when you find the parts.

phantomfixer Posted September 3, 2021 Share #3 Posted September 3, 2021 I dig the helmet and the cut out visor cover...the early earcups are cool.... the screws on the visor look like hardware store machine screws, same with the right nape strap screw...LOL looking at the inside, yeah those screws have got to go .... but overall a nice shell...I dig it...

72psb Posted September 3, 2021 Share #4 Posted September 3, 2021 A very nice prospect for a full resto. PM if you want parts or info. Link to comment Share on other sites More sharing options...
Vark_07 Posted September 4, 2021 Share #5 Posted September 4, 2021 I'd say it might be an early example of the third version HGU-2A/P based on the 22-P shell that was issued in 68-69 or so. These latest 2A/Ps did not feature the 3 iconic shell's cooling holes of the earlier variants, which is a major evidence I noticed on your pictures. Full plastic visor housing like yours, lacking the metal or plastig additional edges on the visor lock track iconic of the early versions, appeared on the mid-60's examples. Finally, the fact that the bayonet receivers were monted downwards indicate the latest "J"-bayonets fitted on the MBU-5/P mask, older in-line or "T"-bayonets typical of the early 60's would have had the receivers mounted straight. So, my feeling is that it is a mid to late 60's HGU-2A/P shell. Clearly not an HGU-33/P anyway 😉. Apart from that, it indeed sports the main characteristics of the -2A/Ps : spring-loaded earcups of the H-154/AIC headset with grommets / studs to attach it externally (the H-154A headset variant without metal arms fixed with velcro on foam pads was introduced in the late 60s / early 70's), a thin tan edgeroll beading, and the full plastic visor housing with a custom-made "gullwing cut". (careful though, it seems to miss the side nylon spacer tracks for the visor, here you have the visor housing directly screwed on the shell...) A nice shell from the HGU-2A/P series anyway, and a good starting point for a restoration project ! Link to comment Share on other sites More sharing options...
Alamo Posted September 5, 2021 Author Share #6 Posted September 5, 2021 Thanks to everyone so far on the info, it's greatly appreciated and i would like as much input as possible no matter how small.....As i said before my brother gave this to me and said i should clean it up , paint it anyway i want and put on display....He had bought two helmets and took parts off this one to make one good helmet.I was building a lot of WW2 plane models at the time and had gotten pretty good with an airbrush so i guess he thought i would do a good job on the helmet as he had no use for it anymore...I saw his helmet after he finished & it was really nice .I don't know what he took off this one, i think he told me the visor,liner and i assume the tracking since there is none on mine . He passed away in 2002 so i'm going to put this helmet back together, maybe not exact or period correct but it will be nice when i'm done. He also gave me a MP helmet from the Vietnam era which i just sold to help fund this project.I'm still learning so if anyone has any suggestions or extra parts laying around please let me know, i don't care if they are used they can't look any worse than what i have!🙃 Link to comment Share on other sites More sharing options...

AMT500E Posted October 1, 2021 Share #9 Posted October 1, 2021 The 1 piece styro liner for the HGU-26p era of helmets will be the easiest to find, either by online auction of direct from one of a couple of places here in the US. If sold correctly it should include the Ensolite rubber brow pad (top in the photos) that glues in after the liner is installed (see photos) Guessing (by the spring loaded earcups) your helmet is/was an HGU 2Ap at origin. If/when you get a liner, be very careful what you choose to use, to attach it to the shell with. Most glues will melt the styrofoam and ruin the instal. You helmet looks like it might be a large size and will need a large liner. The photos are the latest and last 1 piece liner(s) for the HGU-22 sub assembly., medium on the left and the large one on the right. HGU-22 was the last issue of type, supplied as a basic stripped shell from which the desired helmet configuration (T.O.) could be built (single visor, dual visor, etc.) and is identical to previous HGU basic physical designs.

To clarify Identical in all aspects except the 22p did not include the 3 hole feature in the crown of the previous issued, HGU shell. Link to comment Share on other sites More sharing options...
Alamo Posted October 1, 2021 Author Share #11 Posted October 1, 2021 Thanks for the replies......I have a one piece liner i bought but my question is : Obviously this liner won't just pop into the shell so can i cut this liner right down the middle in 2 pieces and install one piece at a time into shell?........Installation is my question.

72psb Posted October 1, 2021 Share #12 Posted October 1, 2021 It should just roll into the shell without to much trouble. They do not cut them up in the factory or the field to get them in. This stuff is not rocket science. Don't over think it, should go together just fine. Link to comment Share on other sites More sharing options...
Alamo Posted October 1, 2021 Author Share #13 Posted October 1, 2021 It's just that i've seen these liners for sale in one piece or 2 pieces and thought that might be the way it is....And where i got it from told me i might have to cut it....These parts are hard to find and expensive so i wanted to ask experts...I don't want to screw 'em up, i'm not buying them again..Thanks for the advice.

Def dont cut it, they do just sorta slide or roll in from the front or rear of the shell. Might have to pull the shell apart with your hands a little from the side like donning a helmet. There were various impact liners for the various APH and HGU series helmets. Earlier ones were 2 or 3 piece designs, not cut and then later liners were mostly 1 piece. Depends on what model helmet it was and how many piece it was. Link to comment Share on other sites More sharing options...
