Trying to see if I can get an evaluation on this stuff I have here. I know generally what it is, but if anyone has any specifics, your knowledge would be appreciated. Any idea on value? Thanks in advance.

No idea on value as I only saw part of it plus a lot of unrelated stuff. but the CW-124/GRA-4 was a part of an HF Doublet or Dipole antenna AN/GRA-4. It could be adjusted to any frequency between 2 and 18 MC. The set came with enough MS-44 Mast Sections to make up two 40' masts maybe called AB-86. See TM 11-2651 for the details. However, all that I saw in the photos was one bag and maybe enough MS-44's to fill it. Didn't see any of the actual antenna parts nor any of the guys or guy plates.

The antenna originally dates from early WW-II for use with SCR-299/399/499. The nomenclature was assigned post-war, judging from the pub date on the first TM 11-2651, probably about the time that the NK's crossed the 38th Parallel the first time. The last revision of TM 11-2651 was in 1973, so it had a long service life.
