Wow! Larry, that's quite a study. Great dagger itself, but these two letters make it very special. There used to be a thread with diagram (based on collectors observation)called "Gua %" showing the percentage of the daggers issued to each SA group. So, the score for "gua" Oesterreich was 0.31% only - the same as super rare "W" (Wachstandarte Feldherrnhalle).
