It is available at the ASSIST website, like all the other military specifications. http://assist.daps.dla.mil/docimages/0001/59/31/1291A.PD3 With a quick glance, I don't see the symbol you described, but perhaps a closer inspection will find it. Appear to be an AN (AN 3-20)standard steel type with manufactures marking For a good marking pics see: http://www.vikingbolt.com/sub_pages/specifications/spec_pages/ident_markings/index.htm Upvote 0 Downvote
