On getting to the Archives in Melbourne, I discovered to my horror that I had requested the files on Oboe I (Tarakan) and Oboe II (Balikpapan) but not Oboe VI (Labuan). This meant another trip. I requested one of the two files for tomorrow; the other is Not Yet Examined and won't be available for weeks. However, I had a lucky break: a set of papers on Oboe VI was misfiled with the papers on Oboe II by the Navy. Therefore, I got all the material I was hoping for. The papers in the requested files are probably another copy of the same material.
Heaven knows how I am going to condense this into a 7,000 word paper. Oboe alone deserves its own paper.
