Excellent Grouping and presentation. Thank you for posting.

I have a USN group to a VB-136 pilot interned there. 

This is a good thread on these belts. Tim    

I first read the book "30 seconds over Tokyo" in grade school. The main crew in the book crashed on a beach and the pilot survived the crash but lost his leg and was  scared up badly in the face. In the attached clip from the movie.. I believe Van Johnson plays the Pilot of that B-25 as portrayed in the book.   That took a lot of guts, to go on a one way mission. This is a 14 minute clip from the movie.      

Thats a great helmet!!! Congratulations.... !!!

So, my search for information was successful enough that I felt confident creating a repro guy line set for my SCR-284.   The first photo here shows a picture that was uploaded to the Radio Nerds website.  (I wish I could give credit for it, but I could not determine who that person was.)  It shows the GY-11 and GY-12 Guy Lines wrapped around an RL-28 Reel.  The RL-28 is also listed as a component in TM 11-275 for the radio set.  It shows a number of details like the brass nomenclature tags and the structure of the mast clamp.  The RL-28 in this photo is a variant made from a plastic Bakelite type material.  It was also made from stamped, painted metal.  Using the reel as a gage, it was possible to estimate some of the dimensions to select hardware parts.  The line is identified as RP-11 Braided Twin 70-80# Test. Armed with this information and estimates, I decided to make my mast clamp out of stacked washers.  I used 7/16" x 1-1/4" washers to make the parts.  Shown is my clamp with the parts test-fitted.  Once they were good, I Mig welded the three parts for each side together and added the hinge rivet and riveted eye hooks (with the riveting simulated by welding on washers to the hardware used to make those pieces). For the stakes, the tabulated weights and dimensions data in the radio set TM along with the lists of Ground Pins (GP) on the Radio Nerds website suggested very strongly that the GP-27-A Stakes were simply commercial, galvanized, 80d nails / spikes.  This seems to make sense.  No need to go through any sort of specialized design and contracting process during the exigencies of the wartime economy to get some specialized "ground pin" when an existing and commonly available nail could be sourced.  At any rate, I have used commercial, galvanized, 80d nails for my own GP-27-A Stakes. The rest of the photos show my guy line kit and a test setup with my SCR-284 Radio Set.  This was pretty easy even by myself.  I could see that 3-4 experienced guys could set this up in just a couple of minutes.  As it was, I was able to set up and guy the antenna in less than 10 minutes, and most of that time was spent going back and forth adjusting the position of the stakes and lines to get the antenna as vertical as possible. One thing I will do is replace the twisted OD line with braided cotton line.  I had to wait to get the braided line, but it finally arrived.  I used the twisted OD line based on a photo that another collector sent me of his original GY-12 Guy Line.  I suspect that his is a postwar French military item (or possibly a late-war US manufactured item).  It not only varied in the line material, but also in the way the line is attached to the hardware.  His GY-12 has the line attached with two overhand knots with the running end whipped to the standing end.  The set shown on the Radio Nerds website shows the RP-11 Twine (probably) sewn into a loop around the hardware with the sewn portion reinforced by whipping.  Eventually, I'll modify my guy lines to replicate this method of construciton. Happy collecting!

My great great grandfather had command of the unit when It was designated as the 121st and then after their redesignation my great grandfather had command of the unit for 5 years at the geneseo armory. This is an article about my grandfather: https://www.thelcn.com/news/local/recipient-s-service-is-widespread/article_babdc8a0-238e-57a2-8369-48c75e1b5685.html   Someone also did a not so great interview of my great grandfather in the 2010s and here is some of the transcript: ROBERT: Well, I had a lot of experience with the armory, as a kid my father was the superintendent of the village there for about 35 years, so I spent a lot of time at the armory. Consequently, I ended up joining the National Guard when I was 17 at the end of my high school senior year. And I went to officer's candidate school and came out as a second lieutenant and eventually had command of the unit in Geneseo here for five years.   KRISTEN: No way!   ROBERT: The last year I was there they built the new armory which has been there for a long time now. The armory used to be an old farmhouse in the same location and they just used the rooms for officers and things like that and built a drill hall on the back of it which was a good sized building. Then the new building was for a cavalry unit so they had 72 horses there at one time. Right there in the village. And that stable is now used by the present guard unit and what they did was build on the end of that and connect it to the riding hall with the sawdust tarmac in there and they put concrete floor in and it was an armory unit when I was there. And now they're an infantry unit and they've been called up three times since 9/ 11. 

how long ago was that?

Beautiful helmet! Congrats. Not an expert either, but that's an early Schlueter and the Hawley liner is obviously very early WW2.  Who knows?      You need a web lace to pull together the suspension.  They are readily available, I believe J. Murray has originals.
