These are great but I was wondering if there are any reports not listed? I'm here on Kwajalein and I've come across a most peculiar primer. I can’t find it in OP 1667, The fischer-tropsch reports or your C.I.AMM report. Its slightly resembles a No.2 primer but… the end of the primer is square and around the rim of the head is stamped the Japanese Navy Anchor, a 16•5 and a π 65 . It's approximately 3.5" (89mm) long and approx. 2cm in diameter. I'll try and post a photo tomorrow night. If you have any suggestions please let me know. Thanks in advance!!
