Bob Hudson Posted March 16, 2021 Share #1 Posted March 16, 2021 These came my way last week - I always enjoy finding the artifacts of Naval aviation (maybe because my dad was a career Navy aircraft fixer). These helmets from a career Navy pilot have a problem that affects a lot of military flight helmets: foam used for padding and around the earpieces interacts with vinyl coverings used on the ear pads and to insulate wire. The process basically melts the foam. We've discussed this on the forum in regards to putting helmets and caps with vinyl headbands on foam heads, but in the case of these flyer's helmets the foam and vinyl are installed at the factory. It makes for a mess but luckily it's on the inside and can be cleaned up sort of. The outsides still can still look cool even if a couple parts are missing, which is not uncommon I've found. This is a GENTEX APH-6D, dated 1977, I believe. ] Link to comment Share on other sites More sharing options...
Bob Hudson Posted March 16, 2021 Author Share #2 Posted March 16, 2021 This is a a SCOTT PRK-37/P from 1982. The foam is all melted on the wires and inside the earpads, but inner shell looks prety good. Link to comment Share on other sites More sharing options...

mohawkALSE Posted March 16, 2021 Share #4 Posted March 16, 2021 Those are damn fine pieces, especially the PRK-37/HGU-33. The foam doesn't look like it did too much damage, Ive seen way worse even after cleaning. Thats cool seeing the 14P mask using the in line amp setup vs the large delta block amp on the nose. As usual the mini regulator is missing, I think the re use them alot so they keep those when a pilot takes his helmet and mask. Link to comment Share on other sites More sharing options...
boxerdogi Posted March 16, 2021 Share #5 Posted March 16, 2021 Great group of helmets! I concur.....flight helmets and gear are hard to pass up in any condition. Link to comment Share on other sites More sharing options...

Vark_07 Posted March 16, 2021 Share #7 Posted March 16, 2021 Wow, no matter the few parts missing, these are definitely beautiful well-worn shells and masks, congratulations 😉. Love them this way ! The asymetrically twin-arrow taped HGU-33 is a beauty, not to mention the rare in-line amp on the MBU-14. Great pieces of flight gear, I'm envious.

I found a washer in my junk pile that - after some paint - works for now. The bottom washer is the original: Link to comment Share on other sites More sharing options...

The PRK-37/P was the shell assembly that many USN / USMC helmets of the 80's were based on. So, depending on the equipment fitted on the shell (liner, visor housing, communication etc.), the PRK-37 took various nomenclatures. See https://www.flighthelmet.com/info/prk.htm for detailed informations and all the PRK-37 based models 🙂. Link to comment Share on other sites More sharing options...

I just found some flight gear inspection records and through that learned he was with VRC-30 Fleet Logistics Support Squadron 30, one of only two active, carrier-capable, Fleet Logistics Support squadrons. The record for that calls it HGU 47/P Link to comment Share on other sites More sharing options...
Bob Hudson Posted March 16, 2021 Author Share #13 Posted March 16, 2021 So it's an HGU 47/P for use in the Grumman C-1A Trader Link to comment Share on other sites More sharing options...
Bob Hudson Posted March 16, 2021 Author Share #14 Posted March 16, 2021 Here's the original record for the PRK/HGU 33 helmet and the Navy does call it HGU-33/P. Link to comment Share on other sites More sharing options...

Vark_07 Posted March 16, 2021 Share #16 Posted March 16, 2021 Love the matching VT squadron tape job on this HGU-33, for sure ! That's a good thing you have all the records, they do come in handy to confirm our guesses 🙂. Quote HGU-47(V2) : PRK-37/P shell, EEK-4A/P single visor, PRK-40 liner assembly, and Headset boom microphone is attached, and the CX-13155/A communications cable is used. No amplifier is used. Used by pilot, co-pilot and crew-members on the following aircraft: C-1A , C-2A. Interestingly enough, what your records tell (plane type, shell nomenclature) would indicate that at some point, your APH-6D was "renamed" on the paperwork as an HGU-47/P 2nd version (the only to be used with C-1A, see quote above). As I quoted above, we see in your pictures that it indeed features the CX-13155/A com cable, M-87 boom/mic, and the 2-part styrene liner assembly with fitting pads... almost everything, except the PRK-37 shell ! I guess this change in the nomenclature means these late APH-6s were used along with the "real" 47/Ps during some time with no particular distinction in the early to mid 80's, prior to being entirely replaced by PRK-37-based helmets on the squadron's shelves. PS : the tape job on the APH-6D / "HGU-47" sure matches the VRC-30 colors as well, this pilot had a keen eye and a true taste for decorating his helmets.

mohawkALSE Posted March 17, 2021 Share #19 Posted March 17, 2021 Nice to have those log records, those are the details I love to have when collecting aviation related stuff. I had bought a parachute system from a Marine OV-10 Bronco and it came with all the log records which i thought was cool, Showed the aircraft it was from.

Most pilots did not tape their own helmets. Squadron assigned Parachute Riggers almost always did the squadron tape jobs. Taping helmets really is a talent and if an individual PR was really good at taping helmets, then he did ALOT of the helmets. I really like these helmets and gear!!!

With parachutes, life rafts, life preservers, GPS locators, infrared strobe lights and assorted signaling devices, naval aviators are better equipped than ever to aid in their own rescue and survive a mishap." Here's some more of the records of what the paraloft riggers maintain. Link to comment Share on other sites More sharing options...
